Paul Reiser as Dr. Sam Owens: Dr. Owens oversees operations at Hawkins Lab. Reiser is best known for his role on '90s sitcom Mad About You.

Cara Buono as Karen Wheeler: Karen is Mike and Nancy's mom. She is known for her supporting role on Mad Men. Joe Chrest as Ted Wheeler: Ted is the patriarch of the Wheeler family. Chrest's past credits include 21 Jump Street and Deepwater Horizon. With the end of the world on its way, we hope that Will can find the strength to finally be honest and that his personal storyline will have a satisfying end, even without Mike's reciprocal feelings. David Harbour as Jim Hopper: Habour plays Hawkins' sheriff, Jim Hopper. He was last seen in the Hellboy reboot. There isn't a total count of episodes yet, but while appearing on the Happy Sad Confused podcast, Matt Duffer revealed that season 5 will be regular-sized, not super-sized like season 4 (which had a total runtime of nearly 13 hours). “The only reason we don’t expect [it] to be as long is, this season, if you look at it, it’s almost a two-hour ramp up before our kids really get drawn into a supernatural mystery," Matt said. "You get to know them, you get to see them in their lives, they’re struggling with adapting to high school and so forth, Steve’s trying to find a date, all of that. None of that is obviously going to be occurring [in Season 5]."I feel like a horse getting ready and the gates are about to open, there's all of this drive and all this passion to do it," said Harbour said while speaking to The Hollywood Reporter. Natalia Dyer as Nancy Wheeler: Nancy Wheeler is Mike's older sister and a recent graduate of Hawkins High. Byer was last seen in Netflix's Velvet Buzzsaw. This emotional arc for him is what we feel is going to hopefully tie the whole series together. Will is used to being the young one, the introverted one, the one that’s being protected. So part of his journey, it’s not just sexuality — it’s Will coming into his own as a young man.” What will happen to the gates?

In the same interview, Ross Duffer elaborated even more about Will's storyline in season 5: “Will really takes center stage again in 5. This emotional arc for him is what we feel is going to hopefully tie the whole series together. Will is used to being the young one, the introverted one, the one that’s being protected. So part of his journey, it’s not just sexuality — it’s Will coming into his own as a young man.” Misha Kuznetsov as Ozerov: Ozerov is the Commander of the Russian operation to re-open the Upside Down gate in Hawkins. Kuznetsov was previously seen in The Man From U.N.C.L.E. Meanwhile we wouldn’t suggest you hold out hope for the return of fan-favourite Eddie Munson. No matter how tempting that fan theory looks.Finally, as to what we can expect, the Stranger Things writing staff gave us a clue when they Tweeted: Maybe I'd be, like, a figment of [Dustin's] imagination or something. Like, if there could be some kind of room for something like that, something a bit supernatural." Andrey Ivchenko as Grigori: Grigori is a Russian hitman and liaison between the Russian army and Mayor Kline. Ivchenko's previous credits include Jane the Virginand xXx: Return of Xander Cage.

This teensy glimpse into the end begins: "DARKNESS. The sound of COLD WIND. GROANING TREES. And... A CHILD'S VOICE. Singing a familiar song:" Priah Ferguson as Erica Sinclair: Ferguson plays Lucas's sister Erica. She is known for roles in 2018's The Oath and Atlantaon FX. Perhaps Max's near death end in season four could pave the way for an even more upsetting story arc for the character going forward? We have a while to shoot and to edit but we're going to work as hard and as fast as we possibly can to get it to people because I know they love the show as much as we do and I can't wait for them to see what's up next, it's really exciting stuff. The scripts are great."

An encounter with the Upside Down evolves into a grand adventure for video game-loving twin brothers living on the outskirts of 1980s Tokyo.” Being a writer is a hard job. It deserves respect. If we respect each other, we can cultivate a kinder, more inclusive, more collaborative environment for everyone that’d be nice.” Speaking on the TODAY program, Sadie said, “We know that it’s happening and that it’s the last season, so it’s going to be emotional, I’m sure,” adding, “Spoiler-free, just with the way my character ended in season 4, I have no idea what is going to happen. But I’ll be there.” Time Skip It's interesting, whenever she sort of blatantly throws herself into danger, I think, because there [was] something about her initially, at least, that felt maybe a little more timid, and a little more played by the rules. I think things like Season One, even going into the tree, the first time she got a gun, and a lot of times in this season, where every time she's just kind of like, "I don't care about necessarily me, or, the fact that I'm not thinking about it as much as I'm trying to figure this out, or get to the bottom of it or stop something". It says a lot that she's just very kind of focused. She's not perfect, and I think she makes a lot of mistakes. Joe Keery as Steve Harrington: Steve now works at ice cream parlor Scoops Ahoy with Robin. Keery was last seen in the indie horror film Slice.
