Stranger Things season 4 release date, likely cast, and that amazing fan theory

As ever with Stranger Things, the moment the third season has finished, the question on everyone’s lips is this: will there be a Stranger Things Season 4 on Netflix? And, when can I get my tiny telekinetic hands on it?

Stranger Things Season 4 is yet to be formally announced (or formally renewed by Netflix), but all the chatter around the show suggests it will happen – with a possible life beyond that as well. And friends don't lie, right?

In an interview with Vulture, Ross Duffer suggested the series would be "a four-season thing and then out." And, we certainly can't imagine Netflix pulling the plug early – though in response, series producer Shawn Levy clarified that "The truth is we’re definitely going four seasons and there’s very much the possibility of a fifth. Beyond that, it becomes I think very unlikely" (via Entertainment Weekly).

While the mega-hit sci-fi / horror / adventure show was originally intended as an anthology series, much in the vein of American Horror Story, the popularity of its adorable child actors ensured that Netflix fans would get more than just one helping of the cast.

Cut to the chase

  • What is it? The fourth season of Stranger Things
  • Where can I watch it? Netflix
  • When will it be released? Late 2020 / early 2021 seems likely

Stranger Things first landed on Netflix in 2016, and has been one of the biggest Netflix Originals series ever since.

Steeped in 80s nostalgia, the show takes influence from countless iconic films and genres from the period, including the works of Stephen King, John Carpenter, and Steven Spielberg – with a killer synth soundtrack underscoring the action.

In a Hollywood Reporter interview, co-creator Ross Duffer noted that "With the kids it's more, yes there's the Spielberg stuff, but that's where it gets a little confusing, because part of it is the Spielberg stuff like E.T. – and because with adults, we really wanted that Close Encounters feel with Joyce and stuff, or Jaws."

Dealing with inter-dimensional beings, telekinetic teenagers, Dungeons & Dragons lore, and all sorts of out-there sci-fi that only gets more fantastic with each season, it's not hard to see how the show has gripped the public's imagination.

The Duffer Brothers' show tends to angle its release date around public holidays such as Halloween for Season 2, or the 4th of July for Season 3 – depending on the time of year within Stranger Things itself. 

We wouldn't rule out a Christmas edition, though we think a Spring season seems more likely – that is, if current plot threads end up leading the show's story to the Chernobyl disaster, which occurred April 26, 1986, which isn't long after the 1985 setting of Season 3. (Yes, this theory is from Reddit, but it's pretty legit, okay?)

There tends to be 1-2 years lead time between each season, so we wouldn't expect Season 4 to be released before late 2020 anyway, and an early 2021 release may be more likely.

Before Stranger Things is officially renewed, there are no official casting announcements, but you can be sure you'll get a lot of the same faces as Season 3 – including Finn Wolfhard (Mike), Millie Bobby Brown (Eleven), Caleb McLaughlin (Lucas), Sadie Sink (Max), and Joe Keery (Steve Harrington). We don't expect to see Keery in a sailor suit for the whole season again, but it was wonderful while it lasted.

Maya Hawke (Robin), a newcomer for Season 3, also quickly became a fan favorite, and will almost certainly be a big presence in the season to come – while Caleb's younger sister Erica (played by Priah Ferguson) will likely continue to enjoy a larger role in the show.

Who won't we be seeing? Spoilers ahead (obviously), but we don't expect to see Dacre Montgomery (Billy) or Alec Utgoff (Alexei) again, though the showrunners could always surprise us. Heck, why don't you bring back Barb while you're at it?

David Harbour's character (Chief Hopper) may well return too – despite seemingly having been killed off in the Season 3 finale. We know an "American" is being kept locked up in a Russian jail somewhere, and Hopper is a likely bet.

With the Byers family moving out of Hawkins at the end of Season 3, it may be that series regulars Winona Ryder (Joyce) and Charlie Heaton (Jonathan) decided to back out from a further season, or will have smaller roles.

Where can I watch Stranger Things season 4?

Stranger Things is one of Netflix's hottest properties, and, like the previous seasons, Season 4 will almost certainly only be on the Netflix platform.

Netflix is a paid-for online streaming service for browsers, TV streaming devices, and mobile and tablets apps. Even the cheapest Basic Plan on Netflix offers access to the whole catalogue of titles for £5.99 / $8.99 / AU$9.99 a month. However, you'll need the Premium Plan to watch the show in the highest video quality possible. You can see a breakdown of all the subscription options in our Netflix plans guide.

Will Stranger Things season 4 be in 4K / HDR?

If you're interested in Stranger Things' good looks as well – as you should be – you may be wondering what video formats the next season will be filmed in.

All three seasons so far have been filmed in 4K Ultra HD resolution, meaning anyone with a 4K TV and a strong enough internet connection will be able to watch in a huge amount of detail. Seasons 2-3 are also in HDR (high dynamic range), meaning an expanded range of colors and enhanced contrast – important for a show awash with bright colors, dazzling neon, and moody skies – though again you'll need an HDR-compatible screen to make the most of it.

Netflix also uses the Dolby Vision HDR format, rather than the competing HDR10+ standard – we know this is a lot to think about with your next TV, but some only support one format over the other.
