Best sci-fi movies: fantastic films to stream or buy in 2017 in the US


Hello, and welcome to TechRadar's list of the best sci-fi movies, which features all of the most intriguing sci-fi movies that you can stream right now on Netflix or Amazon Prime.

You only have to take a quick glance at the box-office numbers to figure out that, over the past several years, science fiction has just dominated every other genre. It’s hard not to see why.

No genre has ensnared audiences with amazement and wonder quite like science fiction. From artificial intelligence and biological mutations to alien creatures (sentient or not) and deep space discovery, science fiction offers a look at a strange new world, and sometimes a future that’s just a little bit closer than we’d prefer.

Only now, just like something you would have seen in the early days of the genre itself, you now hold the power to stream movies directly from the cloud to a variety of streaming devices. And, with sci-fi’s popularity at an all-time high, there’s never been a better time to be a fan of all things strange and unusual.

With that in mind, we’ve sorted through the major streaming providers and found all of the best science fiction films you can conjure with the magic of the internet and, for those who'd prefer home viewing without buffering, found links to the Blu-rays of each movie on this list. 

Oh, and realizing how quickly  films can appear and disappear on Netflix and Amazon Prime Video, we will keep this article updated. So, if you don't see anything you like right now, keep checking back to see if your favorite movie is ready to stream.


A hellishly fun action-adventure film

Date: April 2004 | Director: Guillermo del Toro | Stars: Ron Perlman, Doug Jones, Selma Blair | MPAA rating: PG-13 | Runtime: 122 min

Some good humor
Fantastic world building
It's a goth version of Justice League

A great script, practical effects and nigh-perfect casting all come together to make Hellboy a modern sci-fi cult classic. 

Hellboy is the story about a demon who fights for the forces of humanity while in the service of the Bureau of Paranormal Research and Defense. When the forces of evil, led by Rasputin himself, endangers all life in the world as we know it, Hellboy and his partners must now step in and save the day. 

This surprisingly emotional film is based on the well-known Dark Horse comic series of the same name, and it was skillfully brought to life by the singular vision of acclaimed director Guillermo del Toro, who is known for his peculiar in-camera special effects. While an R-rated reboot starring Stranger Things actor David Harbour is currently incoming and sure to be a raucous good time, the 2004 original is a watershed cult film that should be high on your must-watch list.


Here be monsters

Date: January 2008 | Director: Matt Reeves | Stars: Lizzy Caplan, Mike Vogel, Jessica Lucas | MPAA rating: PG-13 | Runtime: 85 min

Monster's origin is a question mark
Shaky cam the ENTIRE movie!

Most people think of Cloverfield’s brilliant marketing campaign way before they actually remember the movie, but it’s still worth watching this thrilling monster movie event directed by one of today’s brightest cinematic minds – Matt Reeves (War for the Planet of the Apes, the upcoming Batman film).

The film revolves around a group of New Yorkers that find themselves trapped as a terrifying monster falls on New York City. The survivors, with the help of a portable camera, attempt to document the atrocities that follow.

Now, while Cloverfield likely won’t go down in history as a sci-fi masterpiece, this handycam-riddled thriller has already gained quite a faithful cult following and received a distantly related sequel (essentially in name only, but still). If you’re looking to kill some time, you certainly can’t go wrong with Cloverfield. Just don’t think about it too much.

Ex Machina

Bladerunner eat your heart out

Date: April 2015 | Director: Alex Garland | Stars: Alicia Vikander, Domhnall Gleeson, Oscar Isaac | MPAA rating: R | Runtime: 108 min

Deeply profound
Gets your gears turning
Maybe too deep
But, like, are we all androids?

Artificial intelligence obviously is one of the oldest tropes in the science-fiction genre, but Ex Machina stands as one of the most interesting and wholly unsettling movies in recent history regardless.

Ex Machina tells the story of a programmer, Caleb Smith, who wins a contest that sends him to the estate of his firm’s CEO, Nathan Bateman. Once he arrives, Caleb discovers that he’s been unwillingly selected to be the human component in a Turing test to discover the consciousness and abilities of Nathan’s AI creation, Ava. The moral lines begin to grey for Caleb as he starts to realize the implications of Nathan’s invention. 

Writer and director Alex Garland essentially lives neck-deep in the grey area of ethics with this film, weaving together complex characters and themes that will keep you thinking long after the credits have rolled. If you’ve never seen it, put on your thinking cap and prepare for an intriguing thriller of a sci-fi movie.

The Road

Cormac McCarthy's literary classic looks great on the big screen

Date: December 2009 | Director: John Hillcoat | Stars: Viggo Mortensen, Charlize Theron, Kodi Smit-McPhee | MPAA rating: R | Runtime: 111 mins

Good father/son film
Can Viggo Mortenson be my dad?
Get ready for a lot of grey
The future is bleak

In classic post-apocalyptic style, The Road is all about survival. After Earth falls prey to calamity, a man and his son take the long journey across America to the ocean, fighting to hold on to their soul. All around them are bloodthirsty gangs who would see them apprehended as slaves, or much worse. 

Although there are hundreds of films in this genre and tone, execution really is everything. John Hillcoat’s vision comes across flawlessly on screen and packs an emotional punch that won’t leave you quickly. And with phenomenal performances from Viggo Mortensen and Kodi Smit-McPhee, The Road is a worthy entry in the ever growing list of post-apocalyptic science fiction movies.

Star Trek Beyond

Set phasers to fun!

Date: July 2016 | Director: Justin Lin | Stars: Chris Pine, Zachary Quinto, Zoe Saldana | MPAA rating: PG-13 | Runtime: 122 min

Pine and Quinto are outstanding
Zoe Saldana plays ANOTHER alien love interest
Beastie Boys? Again?
You get a lens flare!

After Star Trek: Into Darkness left some (not all) fans confused or disappointed on the direction the promising reboot was heading in, Fast and Furious director stepped in to put some new life into the third installment. The result was a fun and fast paced romp that may have stumbled at times, but still delivered the type of deep space adventure that long time Trekkies had been yearning for. 

The young cast is as electric as they’ve ever been, including a heartfelt final performance by Anton Yelchin as the fan favorite Pavel Chekov. Idris Elba plays an intimidating, if forgettable villain that would have been right at home in a story arc of Star Trek The Next Generation. In the end, Beyond isn’t a cinematic masterpiece by any stretch, but it’s still an exhilarating entry in a franchise that helped build science fiction into the cultural phenomenon it has become.

Jurassic Park

Unearth this seminal classic

Date: June 1993 | Director: Steven Spielberg | Stars: Sam Neill, Laura Dern, Jeff Goldblum | MPAA rating: PG-13 | Runtime: 127 min

Smart 'what if?' scenario
T-Rex is the best character
Don't watch in the bathroom
Raptors are evil in the original

Even to this day, Steven Spielberg’s adaptation of Michael Crichton’s exciting novel, Jurassic Park, exists as a benchmark for the entire science fiction genre. With extremely well written characters, special effects that have aged surprisingly well and a solid premise to hold it all together, it’s pretty hard to find any problems with Jurassic Park. 

If you’ve been living under a rock and have never seen it, Jurassic Park follows a group of scientists who find themselves on wealthy philanthropist John Hammond’s island, the home of a soon-to-open theme park with living, breathing dinosaurs. But, when a storm disrupts the power on the island, their “walk in the park” becomes a waking nightmare. 

Even if you've already taken the ride before, Jurassic Park is a tremendous sci-fi glory that should be enjoyed again and again. 

Iron Man

Witness the birth of the MCU

Date: May 2008 | Director: Jon Favreau | Stars: Robert Downey Jr., Gwyneth Paltrow, Terrence Howard | MPAA rating: PG-13 | Runtime: 126 min

Robert Downey Jr finds his best role
It really ties the room together
Tony Stark is a bit much
Like, he's unbearable at times

Looking back at 2008, all of the weight of the still new Marvel Cinematic Universe rested entirely on the shoulders of Iron Man, a comic book character with a ton of potential, but not much popularity in the mainstream. But that all changed almost overnight thanks to this fresh and unique origin story and the inimitable presence of Robert Downey Jr. 

Director Jon Favreau turns this classic rags to riches story on its head, taking the arrogant billionaire arms dealer named Tony Stark and tearing him down until he becomes the hero we would all come to love. Although the villain of the film is disappointing (reminder: it’s an MCU film), the humbling journey of Tony Stark is enough to drive the plot forward and is responsible for the very existence of the current Marvel Universe. If you haven’t seen this one in a while, watch it again and return to the simpler days of superhero films.

The Terminator

I'll be back ... with some popcorn

Date: October 1984 | Director: James Cameron | Stars: Arnold Schwarzenegger, Linda Hamilton, Michael Biehn | MPAA rating: R | Runtime: 107 min

Career-defining role for Arnold
About as classic as you can get
But that timeline, though
Terminator 2 is probably better

This film didn’t make the Governator a household name for no reason. Over 30 years since its release, The Terminator still stands as a landmark in the science-fiction genre, and is arguably James Cameron’s crowning achievement. 

If you’ve never seen this classic sci-fi/horror flick, The Terminator tells the story of a woman who’s on the run from a cybernetic assassin from the future, and the man who was sent back to save her. While the franchise went completely off the rails after the second installment, the original film is a harrowing and refreshingly focused tale of survival, featuring chase sequences that are truly what nightmares are made of.

This original sci-fi horror classic remains as timeless as Schwarzenegger himself and should be near the top of your streaming list if you’ve never seen it.

E.T. The Extra Terrestrial

E.T. was kiddish, but it's still one of Spielberg's best

Date: June 1982 | Director: Steven Spielberg | Stars: Henry Thomas, Drew Barrymore, Peter Coyote | MPAA rating: PG | Runtime: 115 min

Heartwarming friendship
Good message about calling your parents
The target audience is five year olds
Reese's Pieces product placement

If there was ever a staple in the sci-fi genre, it’d probably be E.T. 

Steven Spielberg’s heartwarming tale of an innocent alien stranded on Earth and the young boy who welcomed him in remains an iconic family classic some 35 years since it first hit theaters. From Reese’s Pieces to that famous shot of Elliot and E.T. flying their bike in front of the moon E.T. is brimming with imagery that conjures up all the nostalgia and happiness of childhood wonder. 

Even if you’ve seen it a hundred times, E.T. is certainly a worthwhile stream in your sci-fi marathon.

The Matrix

Clear your mind (and your schedule) before watching this classic

Date: March 1999 | Director: Lana Wachowski and Lilly Wachowski | Stars: Keanu Reeves, Laurence Fishburne, Carrie-Anne Moss | MPAA rating: R | Runtime: 136 min

Gets better every time you watch it
Keanu Reeves was born to be Neo
Let's not talk about the sequels

While many of the films on this list could be called “great” and “groundbreaking”, there are few that could be labeled “generation defining”. 

The Matrix follows a hacker named Neo, whose eyes are opened to his world for what it truly is – a simulation created by robotic overlords that live off of the humans who created them and is maintained by the mysterious Agents. Once unplugged, Neo and the crew of the Nebuchadnezzar fight the Agents at every turn and struggle to set humanity free.

When the Wachowski’s delivered The Matrix in 1999, the world had never seen anything like it. Blending martial arts-inspired choreography with the most groundbreaking effects ever put to screen at that time, The Matrix was and is a marvel to behold. Even as some of the effects begin to age, the ingenuity of the script becomes more evident. 

Although the sequels sadly never lived up to the promise of the original, The Matrix is a marvel to behold and a hallmark in science-fiction history. 

Rogue One: A Star Wars Story

Movie nights are built on hope

Date: December 2016 | Director: Gareth Edwards | Stars: Felicity Jones, Diego Luna, Alan Tudyk | MPAA rating: PG-13 | Runtime: 133 min

Fills in the gaps perfectly
Introduces great new characters
None of whom you'll see ever again
All the characters you like are CGI

As the first film outside of the saga and the first prequel since Jar Jar Binks, Rogue One: A Star Wars Story had a lot riding on it. It had to strike a balance between originality and familiarity that could have easily backfired and been rejected by old and new fans alike. Thankfully, Rogue One was a rousing success all across the board. 

Taking place before the original Star Wars, Rogue One tells the tale of the brave band of rebel spies led by the tenacious Jyn Erso who risked everything to steal the plans to the fearsome Death Star. The forces of evil, led by Director Krennic, Grand Moff Tarkin, and Darth Vader himself meet the rebels in combat to prevent their plans from falling into the wrong hands. 

The final result of Rogue One was a gritty war film that wasn’t perfect, but stands as an excellent entry into the already expansive Star Wars universe. From a visual perspective alone, this is well worth the stream.


When the rules just don't apply

Date: September 2012 | Director: Rian Johnson | Stars: Joseph Gordon-Levitt, Bruce Willis, Emily Blunt | MPAA rating: R | Runtime: 113 min

Like Twilight Zone with guns
Not sure that's how physics works...

Director Rian Johnson is positively oozing with creativity and character, a trait that helped him land his current gig as director of Star Wars: The Last Jedi. But before we get his undoubtedly unique spin on a galaxy far, far away, it’s worth revisiting the film that got him there. 

Looper is a time-tangled mobster film that positively shatters any mold it could fit in. It pushes the boundaries of what makes the sci-fi genre what it is and the result is a singular film that will be talked about for generations. While the ride is a little rough at times, Bruce Willis and Joseph Gordon-Levitt both shine in this sci-flick that needs to be seen to be believed.

2001: A Space Odyssey

"Open the DVD player tray, HAL"

Date: May 1968 | Director: Stanley Kubrick | Stars: Keir Dullea, Gary Lockwood, William Sylvester | MPAA rating: G | Runtime: 149 min

Has a ton of iconic sci-fi moments
Came from the '60s!
It's a slow burn
HAL, open the doors bro

What can be said about Stanley Kubrick’s science-fiction masterpiece that hasn’t already been said a thousand times? Simply put, 2001: A Space Odyssey is the genuine article to which just about every space film has to endure comparison -- for better or worse. 

Although not everyone considers it Kubrick’s best work, it has to be considered amongst the most ambitious films ever made, narratively and visually. Any true fan of the genre must make the pilgrimage through this unusual, iconic, and mesmerizing space epic directed by one of the all-time great filmmakers.

Doctor Strange

Take a trip with the Doctor

Date: November 2016 | Director: Scott Derrickson | Stars: Benedict Cumberbatch, Chiwetel Ejiofor, Rachel McAdams | MPAA rating: PG-13 | Runtime: 115 min

Bright and ultra-colorful
Cumberbatch can do no wrong
Strange is just a little too good
He knows more than a god

As Marvel’s cinematic success has expanded, so has their creative sandbox. A Doctor Strange movie would have been a fool’s dream just a decade ago, but now the master of mystic arts has his own film with top-notch special effects, a dream team cast, and a talented director to helm it. What a time to be alive! 

For those not in the know, Doctor Strange follows the story of Stephen Strange, a talented surgeon with an ego to match his skillset. After a car accident, Strange loses the use of his hands and loses his sense of purpose. On his journey to find healing, Strange stumbles into the mystic arts and finds a deeper purpose in magic, spirituality and sorcery. 

While formulaic at times, Doctor Strange is a blast from start to finish, riddled with humor and enough sci-fi and sorcery babble to make your head spin. 

The Iron Giant

Find a new best friend with The Iron Giant

Date: August 1999 | Director: Brad Bird | Stars: Eli Marienthal, Harry Connick Jr., Jennifer Aniston | MPAA rating: PG | Runtime: 86 min

Family friendly sci-fi
Vin Diesel voices the giant
Skews a bit younger
Parents are bad at their jobs

Before Brad Bird gave us animated classics like Ratatouille and The Incredibles, there was the Iron Giant – the story of an alien robot who forms an unexpected friendship with a young boy in Rockwell, Maine. When government forces become skeptical of the Iron Giant’s intentions, the boy must find a way to save his new friend from destruction. 

Although the Iron Giant has maintained a steady following, it’s never gotten the widespread recognition it deserves for being a thoroughly brilliant piece of science-fiction filmmaking. If you skipped out on this film, hop on over to Netflix and give this modern animated classic a shot. 

Star Trek II: The Wrath of Khan


Date: June 1982 | Director: Nicholas Meyer | Stars: William Shatner, Leonard Nimoy, DeForest Kelley | MPAA rating: PG | Runtime: 113 min

That's all you need to know
New Khan is pretty great, too
You could just watch Into Darkness

Of course Star Trek gets two spots on this list! We’re talking sci-fi, right? 

The Wrath of Khan is the follow-up to the original motion picture and reached cinematic and emotional heights that many would argue have never been met again in the franchise. In the film, Kirk, Spock, and the crew are confronted with the enigmatic villain known simply as Khan, someone Kirk had run into years before. As the pieces begin to move, the crew of the enterprise find themselves in a showdown with one of the most powerful villains in the universe. 

With a tight script, a brilliant performance by Ricardo Montalban, and an ending nearly as iconic as Star Trek itself, The Wrath of Khan is what sci-fi is all about. Treat yourself to streaming this one on either Amazon or Hulu.


Mankind was born on Earth. It was never meant to die here

Date: 2014 | Director: Christopher Nolan | Stars: Matthew McConaughey, Anne Hathaway, Jessica Chastain | Certificate: 12A | Runtime: 169 min

Beautiful to look at
A soaring soundtrack
The plot unravels near the end
Too much copying of Kubrick

Chris Nolan aims for the stars with Interstellar and the film suffers as a result. It’s too clever for its own good, with an ending that is pure Kubrick in its obscurity. Despite its flaws, though, Interstellar is still a wonderful, bold movie. It’s set in a time when food has become scarce on Earth so a mission is planned to go ‘interstellar’ and seek out a planet with Earth-like properties seen through a wormhole. Nolan shot a lot of the film with an IMAX camera so visually it’s superb, it’s just a shame the script doesn’t quite match. It’s still worth viewing, though, as a flawed Nolan movie is far better than most movies released.

Eternal Sunshine of The Spotless Mind

Our memories makes us who we are. You can't change the past

Date: 2004 | Director: Michel Gondry | Stars: Jim Carrey, Kate Winslet, Tom Wilkinson | Certificate: 15 | Runtime: 108 mi

A mind-bending masterpiece
Visually inventive
Script sometimes gets lost
Flits between comedy and drama

Michel Gondry’s mind-melding look at memories is light sci-fi but sci-fi nonetheless. Its plot has something of a reverse Total Recall vibe to it, Clementine (Kate Winslet) suffers a bad breakup from Joel (Jim Carrey), to make sure that she suffers no more she undergoes a procedure that will rid her of her memories of them both together. Not to be outdone, Joel goes for the same procedure with sometimes heartbreaking consequences. This is a beautiful, strange movie and still Gondry’s best. He takes a lot of his creative learnings from the music videos he created before Eternal Sunshine and puts these shots to good use in the movies. It may well be the best performance from Carrey, too.

Source Code

Make every second count

Date: 2011 | Director: Duncan Jones | Stars: Jake Gyllenhaal, Michelle Monaghan, Vera Farmiga | Certificate: 12A | Runtime: 93 min

Tight, cerebral storytelling
Keeps you guessing until the end
Story is easy to unpick
The CGI could be better

Duncan Jones second sci-fi spectacle, after the superb Moon, sees Jake Gyllenhaal as Colter. He's a soldier trapped in the body of someone else, who has to relive a train ride over and over until he can figure out who the bomber on the train is. While the plot device is reminiscent of Edge of Tomorrow, it actually has more in common with ‘90s TV show Quantum Leap, with Jones even nodding to this with the casting of Scott Bakula as the voice of Colter’s father. And at only 90 minutes, the film gives you no time at all to breathe, or space to try and figure out just what is going on. This is no bad thing as it also leaves you wanting more.

Mars Attacks

Yikes! They've Landed!

Date: 1996 | Director: Tim Burton | Stars: Jack Nicholson, Pierce Brosnan, Sarah Jessica Parker | Certificate: 12 | Runtime: 106 min

Brilliant '50s alien movies send-up
Superb ensemble cast
CGI looks dated
Bit too silly for its own good

Given Mars Attacks is a spoof of ’50s sci-fi movies and comic books of yesteryear, it’s natural that now Tim Burton’s film looks as dated as the classic movies it was satirizing, thanks to the saturation of early CG. But that doesn’t distract too much from the movie, which is a genius burst of bubblegum sci-fi. The plot is paper thin: aliens travel to earth and want to blow everything up with a giant laser. But with a cast list that’s perfect (Jack Nicholson plays the president, Glenn Close the first lady and even Tom Jones makes an appearance) jokes bathed in irony and some brilliant Ed Wood style effects, the film still holds up today as a manic opus.  


The king will rise

Date: 2014 | Director: Gareth Edwards | Stars: Aaron Taylor-Johnson, Elizabeth Olsen, Bryan Cranston | Certificate: 12A | Runtime: 123 min

Brilliant epic feel to the movie
An adult, focused retelling
Not enough Godzilla!
Bit too slow going

Gareth Edwards had only one movie on his resume (the low-budget Monsters) before he was given this behemoth of a movie. Despite his slim portfolio he did competent work with the Godzilla legend, even if the tremendous lizard is a little camera shy at times. Edwards sets his Godzilla tale both in San Francisco and Japan where Godzilla and other monsters are conjured after strange tremors cause a nuclear power plant meltdown. When we do get a glance at Godzilla, the giant lizard looks glorious but these shots are few and far between. Edwards decides to inspire suspense through Spielberg reaction shots and clever camera work which makes this movie a slow burner, rather than the all-out action fest it could have been.  


A journey to the heart of the universe

Date: 1997 | Director: Robert Zemeckis | Stars: Jodie Foster, Matthew McConaughey, Tom Skerritt | Certificate: PG | Runtime: 150 min

Amazing performance from Foster
A thoughtful take on the space genre
Special effects haven't aged well
A little too much 'message'

Robert Zemeckis’ Contact is one of the most brilliant, provocative blockbusters of the last 20 years (it came out in 1997). Based on the novel by renowned astronomer Carl Sagan, the movie illustrates a lifelong hunt for life on other planets by Elli (Jodie Foster) and is a astonishing study or belief and determination. Zemeckis always surprises with his film choices –- this is a director with both the Back To The Future trilogy and Flight in his portfolio –- but he’s perfect for Contact, using at-the-time cutting-edge special effects and subtle-but-brilliant audio cues to highlight the probability of alien life. It’s testament to how good the movie is that only recently have we started to see intelligent sci-fi films back in the cinema (the Planet of The Apes series, Interstellar and Arrival, to name a few) but none of them rival Contact when it comes to stripping down high-concept ideas, making them appeal to a mainstream audience. 

Attack The Block

Inner city vs outer space

Date: 2011 | Director: Joe Cornish | Stars: John Boyega, Jodie Whittaker, Alex Esmail | Certificate: 15 | Runtime: 88 min

Brilliant, original concept
Great ensemble cast
Tries too hard to be a cult classic
Not funny or scary enough

Pop quiz: which low-budget British movie stars a Star Wars hero, an upcoming Doctor Who and is directed by the original writer of Ant Man? That’s the provenance Attack The Block now has, thanks to its stars John Boyega and Jodie Whittaker taking on two of the most iconic franchises and director Joe Cornish now firmly camped in the Hollywood Hills. Before this infamy, though, Attack The Block still stood out as a fantastic slice of sci-fi that’s been given a very distinctive British flavour. Based on the idea that aliens have come to earth and decamp in a South London estate, the film marries two disparate ideas to great effect, creating one of the most original movies around. 


The dream is real

Date: 2010 | Director: Christopher Nolan | Stars: Leonardo DiCaprio, Joseph Gordon-Levitt, Ellen Page | Certificate: 12A | Runtime: 148 min

Highly original blockbuster
Amazing visuals
Lots of ideas but not all of them hit
Dialogue a bit too pedestrian

Christopher Nolan challenges the perception of dreams and reality in this high-octane, high-concept thriller based on a group of thieves who steal through ‘inception’ - putting their victims in a dreamlike state, tapping into their conscience and uncovering a bevy of secrets. Leonardo DiCaprio is the head of the group, who is burdened by his past demons but his latest hit offers him a way out and puts the crew on the ultimate assignment. Nolan paints a puzzling picture with Inception, asking questions but never really offering up answers which will be frustrating some. But stick with it and you’ll be rewarded with one of the most original and entertaining movies in years.
