Foundation season 2: release date, trailer, cast, plot, and more

Get ready: Foundation season 2 is officially breaking of the Apple TV Plus show's Vault and launching on the platform this July.

After a lengthy 18-month wait, one of the best Apple TV Plus shows is returning to our screens this summer (or winter, for southern hemisphere fans), and we can't wait. The arrival of a new Foundation season 2 trailer – complete with Star Trek-inspired visuals and plot – has further whetted our appetite for the ambitious sci-fi series' return, too. In short: role on July.

If you want to learn even more about Foundation's return before its second season makes the jump onto Apple TV Plus, we've got you covered. You'll find more details on its release date, cast, plot, trailers, and more in the sections below. So, what are you waiting for?

Full discretion before we begin: major spoilers follow for Foundation's first season. Potential spoilers for Isaac Asmiov's novels, which the show is based on, and Foundation's second season are also discussed.

Foundation season 2 release date

Foundation season 2 will debut on Apple TV Plus on Friday, July 14. That launch date reveal was made alongside its official trailer (more on this in a moment) and comes four months after Apple confirmed a Q2 2023 release for Foundation's next outing.

The series will return with a one-episode premiere in mid-July, with subsequent episodes released every Friday until the season 2 finale on September 22.

Foundation season 2 trailer

Foundation season 2's official trailer was released alongside its launch date on May 11. And, as we noted up top, it's packed with plenty of Star Trek and Star Wars-inspired imagery, tense combat, political machinations, and tantalizing story beats.

The new teaser shows off some of the new characters audiences will meet in the show's second season (more on these later), a few of whom are gunning for Empire and the Cleon clones specifically. If Lee Pace's Brother Day thought he had a difficult time of it in season 1, he'll need to think again.

Foundation season 2 plot

Full spoilers follow for Foundation season 1.

Here's the official plot synopsis for Foundation season 2: "More than a century after the season one finale, tension mounts throughout the galaxy in Foundation season two. As the Cleons unravel, a vengeful queen plots to destroy Empire from within. 

"Hari, Gaal, and Salvor discover a colony of Mentalics with psionic abilities that threaten to alter psychohistory itself. The Foundation has entered its religious phase, promulgating the Church of Seldon throughout the Outer Reach and inciting the Second Crisis: war with Empire. 

"The monumental adaptation of Foundation chronicles the stories of four crucial individuals transcending space and time as they overcome deadly crises, shifting loyalties and complicated relationships that will ultimately determine the fate of humanity."

Those of us who have read Isaac Asimov’s book series might think we know the direction of Foundation season 2’s story, but the source material can’t be relied on anymore. The show's creators used the books as a basis for the TV adaptation but, by the end of last season, it had diverged from the story in the novels.

Still, there are plenty of unresolved plot threads and new material to explore in the series' next outing. And, thanks to its cast and showrunner David S Goyer, we have a few pointers about how they might be examined in greater detail.

Per Collider, Goyer confirmed that answers to some of season 1’s open-ended questions will be resolved in future seasons. "If there's a question that we haven't answered, there's a reason why we haven't answered it," he teased. "It's not because we forgot about it. It's 'watch this space.'"

One of the biggest story points we need more details on is the revelation that Brothers Dawn, Day, and Dusk are not identical clones of Cleon I. After Eto Demerzel (Laura Birn) killed Dawn’s current (or, rather, previous) incarnation due to the genetic differences that made him an impure clone, it’s revealed all of Cleon’s clones are genetically unique. An anti-Empire resistance group, which included Dawn’s ex-lover Azura, had tampered with the DNA of Cleon I’s host body decades earlier, meaning none of the Empire’s current rulers are identical clones of Cleon I.

Speaking to Newsweek, Goyer teased what this shock reveal may mean for this triumvirate in Foundation season 2.

"Part of the fun of the show moving forward [is] we'll be seeing how different the various Cleons are," Goyer said. "It's part of the jazz that we're playing with Terrence [Mann], Cassian [Bilton], and Lee [Pace] because, even though they're the same actors, some of the characters are going to be very different. One of the things that's exciting about this monkey wrench, that's thrown into the Genetic Empire, is what does that do when you introduce chaos into that system?"

For Pace, the Great Spiral pilgrimage Day undertook in episode 8 foreshadowed the season 1 finale’s big reveal. Speaking to The Wrap, Pace said: "He [Day] looks at his brothers and especially his younger brother [Dawn], who is now shown to be different in all of these ways, and is basically screaming ‘Me too'. I feel the same way you feel. I know we are living under this fantasy that we are all the same man, and I know better now. I can’t un-see what I’ve seen. I can’t forget. I can’t believe that I am Cleon. I have to now believe that I am this person after what I’ve experienced. I think it forever changes the culture inside the dynasty."

The other major plot point from the season 1 finale confirmed a series-long fan theory: Salvor Hardin (Leah Harvey) is the daughter of Gaal Dornick (Lou Llobell). Its final scene is reserved for their overdue meeting – albeit 138 years into the future. Gaal froze her embryo in episode 2, and that fertilized egg went on to become Salvor, who lives on Terminus over a century later. The only reason Gaal and Salvor eventually meet is because of the show’s time travel elements, as well as Gaal occasionally entering cryostasis for decades at a time.

Goyer has been coy about whether the duo’s relationship will potentially grow – the season 2 trailers tease they'll team up for a time before potentially embarking on separate missions. However, he's also provided some context about how Gaal may react to Salvor’s declaration. And, given their respective time travel adventures, how Gaal is strangely younger than her daughter when they’re reunited.

"The story of Gaal and Salvor… I would say the closest analogy would be if someone gave up a child at birth and didn't even know what happened to them," Goyer told Newsweek. "And then one day that adult child knocks on their door and says, 'Hey, mom'. What's a little different is that, at least biologically, Salvor's a few years older than Gaal, which is one of the fun things that you can only do in science fiction. I think Salvor's about 26 or 27 years old, and Gaal is only about 23 years old, 22 years old."

Hardin additionally told TVLine: "These two characters are complete strangers and we'll get to dive into how they navigate this new relationship, as well as the world around them bringing new challenges [in season 2]. They both have traveled years into the future, and for all they know, everything they knew has been left behind. They, potentially, only have each other left. It’s a profound emotion to contemplate, but it is something that requires time to process. Whether or not they have the luxury of time is another question entirely."

Meanwhile, what about the Second Foundation, which fans of Asimov’s book series already know about? As Hari Seldon teased in season 1's final episode, he set up two Foundations at opposite ends of the galaxy – one which the Empire knows about and one it doesn’t. Foundation season 2, then, should take us to this Second Foundation, which is teased in the first trailer.

"It's definitely something we're going to explore," Goyer told Newsweek. "I didn't bring it up just to not mention it again. One of the other things about the Second Foundation in the books is that the Second Foundation also largely develops off-screen, at least in the original trilogy. It appears almost as a deus ex machina. And I thought, for viewers of the show, that wouldn't be playing fair, that we had to see the Second Foundation develop."

As the first teaser reveals, the second Seldon Crisis will form a large part of the second season. The alliance that eventually formed between Terminus, Thespis, and Anacreon in season 1 allowed the trio of outer-rim planets to navigate the First Crisis. But, as Hari’s AI construct told their populations in episode 10, more challenges will be on the way. The books give some indication about what the second crisis is, but it's unclear if Goyer and company will use it ad verbatim or make some creative alterations.

Finally, as for other big plot points, the season 2 synopsis reveals that the Empire will have to deal with a whole host of threats. From Queen Sareth's quest for vengeance to the emergence of the Church of Seldon, and the political infighting to even being attacked by galactic monsters (things don't look good for Day in that final shot of the second trailer), the Cleons have their work cut out. That said, Hari and company do, too, with the Mentalics, the Empire's oppressive nature, and the Second Crisis sure to have a big say in Terminus' (and the wider galaxy's) future. Color us excited.

Foundation season 2 cast

Here's who's returning for Foundation season 2 from its first installment:

• Jared Harris as Hari Seldon
• Lee Pace as Brother Day
• Lou Llobell as Gaal Dornick
• Leah Harvey as Salvor Hardin
• Laura Birn as Eto Demerzel
• Terrence Mann as Brother Dusk
• Cassian Bilton as Brother Dawn

The second season will also introduce new characters, including some from Asimov's works as well as original characters specific to the show.  First, in October 2021, Goyer confirmed more live-action incarnations of individuals from Asimov’s novels will show up.

"With season two, our audience will get to visit more of Asimov’s indelible characters and worlds, including Hober Mallow, General Bel Riose, and all the Outer Suns," Goyer explained. "We’re playing the long game with Foundation and I’m grateful to my partners at Apple and Skydance for entrusting me with this epic. Buckle up. We’re about to fold some serious space."

In a separate announcement, Apple confirmed the identities of 10 new individuals, including those mentioned by Goyer, and actors who will portray them:

• Isabella Laughland (Harry Potter) as Brother Constant, a cheerfully confident claric whose job is to evangelize the Church of the Galactic Spirit across the Outer Reach
• Kulvinder Ghir (Goodness Gracious Me) as Poly Verisof, High Claric of the Church of the Galactic Spirit. Whip-smart and sardonic, he’s also a terrible drunk – intelligent enough to see the path he’s on, but too cynical to change
• Sandra Yi Sencindiver (The Wheel of Time) as Enjoiner Rue, the beautiful, politically savvy consigliere to Queen Sareth. A former courtesan to Cleon the 16th, Rue parlayed her status to become a royal counsellor
• Ella-Rae Smith (Fast & Furious: Hobbs & Shaw) as Queen Sareth of Cloud Dominion. Used to being underestimated, Sareth employs it to her advantage, charming her way into the Imperial Palace with biting wit, all while on a secret quest for revenge
• Dimitri Leonidas (Centurion) as Hober Mallow, a master trader with a sarcastic personality and questionable morals, who is summoned against his will to serve a higher, selfless cause
• Ben Daniels (Jupiter's Legacy) as Bel Riose, the last great general of the Superliminal Fleet and would-be conqueror of the Foundation. Bel is noble to a fault, but his fealty to the Galactic Empire is waning
• Holt McCallany (Mindhunter) as Warden Jaegger Fount, the current Warden of Terminus and guardian of its citizens against external threats
• Mikael Persbrandt (Sex Education) as The Warlord of Kalgan, a monster of a man, coiled with muscle and possessing powerful psychic abilities, and fueled by hate in his quest to take over the galaxy
• Rachel House (Cowboy Bebop) as Tellem Bond, mysterious leader of the Mentallics
• Nimrat Kaur (Homeland) as Yanna Seldon

Poly Verisof, The Warlord of Kalgan, Bel Riose, and Hober Mallow are the only four characters who appear in the books. The other six, Yanna Seldon included, are entirely new creations for Foundation season 2. Little is known about these individuals, but we don't have much longer to wait to find out how they factor into season 2's, and that of the wider TV series', story.

Will Foundation return after its second season?

Apple has only publicly renewed Foundation for another season, but we’d be shocked if more aren’t forthcoming. Speaking to Lovin Malta in January 2021, Goyer revealed his ambitions to tell Foundation’s vast and epic tale, which spans one thousand years of fictional human history. Goyer also confirmed (via Collider) that he initially pitched an 80-episode story before Apple greenlit the show’s first season. And, curiously, Goyer already has the its ending in mind.

If each season comprises 10 episodes, Foundation might run for eight seasons. However, its continual renewal will depend on whether audiences continue to tune in. Apple is notoriously guarded about releasing viewing figures for its in-house movies and TV shows – so much so that no data for Foundation season 1’s episodes, or any of its movies and TV shows, is publicly available.

Is a third season in the offing, then? Apple hasn't said as much, but The Midgard Times suggests filming has already begun on another 10-episode installment. The outlet claims principal photography will only take three months, though, which seems like an incredibly short period of time for a series of this size and scale to shoot for. We'll wait for Apple's official announcement before we believe this one, then.

Foundation season 2 is definitely coming, but its future (Midgard Times report notwithstanding) is unknown past that point. Its first season found its feet with each episode and, providing its successor can improve on the series’ first outing, it'll surely be renewed (if it hasn't already) for another season.
