Stranger Things actress Sadie Sink has given a tantalising hint about her role in an upcoming Marvel film.
The star, who's best known for playing Maxine 'Max' Mayfield in the Netflix hit series, is set to appear in the superhero sequel Spider-Man: Brand New Day, alongside Tom Holland. However, details of her character remain shrouded in mystery.
Fans have been speculating wildly about who she might be playing, with guesses ranging from comic book favourites like Gwen Stacey and Jean Grey to lesser-known characters. But both Marvel Studios and Sony are keeping tight-lipped, leaving fans guessing.
Addressing some of the most popular theories, many of which suggest she'll play a character with similar red hair, Sink told Entertainment Weekly: "A lot of people forget that hair colour can change, but, yeah, I understand all of the theories."
Her comment that "hair colour can change" could hint at her playing Spider-Man's blonde love interest Gwen, especially after his girlfriend MJ, played by Zendaya, lost her memory in the last film, reports the Mirror.
However, there's also speculation that Sink could play X-Men member Jean Grey, a theory that predates her joining the franchise. She said: "That was happening before I even knew that I would be working on this project.
"I was like, 'Wait! What are people talking about?'"
There's a strong chance that the Stranger Things star could be playing a lesser-known character named Rachel Cole, the sidekick of vigilante the Punisher who will also be making an appearance in Brand New Day portrayed by Jon Bernthal.
"People will just have to wait and see," Sink teased. "I'm excited for all of it to maybe be put to rest."
The actress currently has multiple mysteries surrounding her upcoming on-screen appearances, as the fate of her Stranger Things character Max was also left up in the air at the end of season four.
After a tense showdown with Vecna (Jamie Campbell Bower), Max was left in a coma while her friends anxiously await her revival, which may never actually happen.
"For the most part, I think people trust me to keep my mouth shut," she said.
"Press is pretty boring if you can't talk about the episodes - for me, at least. She's in a coma. That's all I can say."
