Stranger Things is three seasons in, and a fourth is on the way, having been officially confirmed by Netflix. Here's everything we know about Stranger Things 4 so far, including the possible release date and plot rumours.

Series creators the Duffer brothers had previously suggested that the show would only run for four seasons before coming to a close, though since then we've heard that it may run a little longer than that. If you want to know what else is on Netflix, we've done a roundup of the best upcoming shows and movies on the platform this month

When will Netflix release season 4?

We don't have any release date for the fourth season yet, so there's no firm answer. So far there's been a gap of roughly a year and a half between each season. Prior to the pandemic, this would have indicated a late 2020 kick-off date. However, filming is now on hold which will likely push the release date back even further. 

What we do know is the title of the first episode of the season, which will be 'Chapter One: The Hellfire Club'. That name is most known from the eighties X-Men comics - a group of villains from The Dark Phoenix saga. This is most likely just a pop culture nod (something this show is infamous for), but who knows? There could be some more hidden clues in this title. 

Watch the trailer

There's no proper trailer with footage from Stranger Things 4 yet, but we do have this announcement teaser:

In February 2020, director Shawn Levy posted the following sneak peek trailer with the tag 'From Russia with love'. 

Who will be in the cast?

The cast hasn't been announced yet for season 4, but we can make a few predictions. It's a fairly safe bet that all of the core cast will return - minus anyone who may or may not have perished (no spoilers just yet).

There are rumours on one particular cast member - Variety has reported that Priah Ferguson has been promoted to a series regular on the show. Ferguson stars as Erica Sinclair, the hilarious younger sister of main character Lucas. Season 3 saw her be featured much more heavily, so this move is unsurprising. 

The third season introduced a number of new characters to the show, such as Cary Elwes' mayor, and we'd hope to see some of them stick around for next time, likely along with a few new additions. We'll update this article as soon as we know more.

Season 4 rumours

With season three still relatively recent it's too early to have anything except speculation about what season four holds. But when has that ever stopped us? Here's what we think/hope we might see - naturally with spoilers for the third season.

Season three ended with the gang successfully closing the gate and destroying the Russian machine - with Jim Hopper seemingly dying in the process.

The post-credit scene (you did watch that, right?) reveals that things aren't so simple: the Russians are still operating in, y'know, Russia, and have an American prisoner (the trailer confirms that this is Hopper) and have presumably gotten the machine there working, since they also have a pet Demogorgon.

What's not clear is if they'll still require some sort of link to Hawkins to keep their contact with the Upside Down alive. And if not, will the Hawkins gang end up on a road trip to Kamchatka, or will there be some other way to link the two plot threads together?

The Duffers have already said that a fourth season could "open up a little bit... in terms of allowing plotlines into areas outside of Hawkins," and the teaser trailer hinted that 'We're not in Hawkins anymore,' so it looks pretty clear that the show is about to branch outside of its defining township.

Then there's Eleven: she seems to have lost her powers, but we would bet almost any money that before the end of season four she'll get them back. Odds are that will also involve a return to Hawkins with the Byers family - they mentioned coming back for Thanksgiving, which could be a very neat excuse to set the next season during the season.

Will Stranger Things season 4 be the last?

Thankfully, no. In an interview with The Hollywood Reporter, the Duffer brothers confirmed that season 4 will not be the last, and that the break from filming has given them the opportunity flesh out the plot. Ross Duffer stated, "[the pandemic] has given us time to look ahead, figure out what is best for the show. Starting to fill that out gave us a better idea of how long we need to tell that story.

We don't know how many more seasons there will be, but considering that originally season 4 was supposed to be the last, we imagine that it can only go on for another few years. But alas - never say never.
