However, while it’s tended to go that way, where their roles in Stranger Things came first followed by an MCU movie or TV show, it’s also gone the opposite on occasion. We’ve included all of them here. And now that Stranger Things is wrapping up, who’s to say this list couldn’t be expanded once the Stranger Things cast start looking for new things to do?
7) Sadie Sink as an Unknown Character

Sadie Sink is one of the bigger stars to come out of Stranger Things. Introduced in the second season, her Max Mayfield becomes the sixth member of “the Party” after Lucas Sinclair, Mike Wheeler, Will Byers, Dustin Henderson, and Eleven. She’s the reckless one of the group, showing herself capable of doing things such as stealing a car. In the first few episodes of Season 5 her body is still comatose while it’s revealed that her mind is trapped within Vecna’s mind.
Sink is currently slated to make her MCU debut in Destin Daniel Cretton’s Spider-Man: Brand New Day. It’s currently unknown which character she’ll be playing, but considering the movie isn’t set to be released for another seven months that’s not but so surprising. However, we’ll probably learn her identity soon enough. For now, we’ll just have to imagine it’s at least one character the fans are theorizing it could be, from Mayday Parker and Julia Carpenter to Felicia Hardy and Gwen Stacy.
6) David Harbour as Red Guardian

A major presence since the beginning of Stranger Things, David Harbour plays, of course, Jim Hopper, Police Chief of Hawkins, Indiana and surrogate father to Eleven. If the remaining episodes of Season 5 end up killing off a big character or two Hopper is on the table, and it would devastate fans.
Harbour made his impressive debut in one of the MCU’s most underrated movies: Black Widow. His Alexei Shostakov aka Red Guardian is both a father figure to Natasha Romanoff and Yelena Belova and a low-rent version of Captain America.
5) Jake Busey as Tony Caine

Known for his roles in movies like The Frighteners and Starship Troopers, Jake Busey has also remained steadily busy on the small screen. For instance, he played Bruce Lowe, journalist for The Hawkins Post, in the third season of Stranger Things.
Busey’s Tony Caine aka The Candy Man was only in two episodes of Agents of S.H.I.E.L.D., in which we learn he was expelled from the S.H.I.E.L.D. Academy of Science and Engineering in his younger days. And, while Caine initially appears to be an adversary, he soon teams with S.H.I.E.L.D. to procure Gravitonium.
4) Joseph Quinn as The Human Torch

Like with Sadie Sink, Stranger Things has proved to be a massive launching pad for Joseph Quinn. His Eddie Munson is widely deemed one of the high points of Season 4. Quinn sells Munson’s love for heavy metal just as he does a lot to make Munson’s final sacrifice one of the series’ most heart wrenching moments.
Marvel finally made a very good Fantastic Four movie with The Fantastic Four: First Steps, and Quinn was just one part that helped it work. Unlike his previous incarnations he’s not quite a show off as much as he’s someone who wants to contribute to the team, solve the mystery of the Silver Surfer, and be a good uncle to Franklin Richards. The Human Torch will next be seen in Avengers: Doomsday next year followed by Avengers: Secret Wars in 2027.
