Sadie Sink was recently busy promoting the upcoming release of the final season of Stranger Things, and now she’s back in London. As reported by TMZ, the actress was spotted in the city. Further reports from @MCUFilmNews on X claimed that she was back in London to film the upcoming Spider-Man: Brand New Day.
Plus, some images have also shown her on the sets of this fourth installment in Tom Holland’s web-slinger film series. In the behind-the-scenes leaked images shared by the Daily Mail, while Holland was seen performing some intense stunts, Sink was also spotted, wrapped in a beige hoodie and khaki coat as she chatted away with the crew.

Her outfit even sparked some real debates online among fans, who have started speculating about the potential character she might be playing in the movie, since that mysterious role has not been revealed yet. But while that’s that, Sadie Sink was also recently asked to describe her character in the movie, and she didn’t hesitate to play coy about it!
Sadie Sink’s Response When Asked to Describe Her Character in Brand New Day

At the recent Stranger Things premiere, Sink was interviewed by Entertainment Tonight about the fifth and final season of the hit Netflix show, which is set to hit the streaming giant with its first four episodes on November 26, the next three on Christmas, and the finale on New Year’s Eve.
That’s when she was asked to describe her character in Spider-Man: Brand New Day in one word as well. To this, she initially said,
I thought this was the Stranger Things premiere! I wasn’t prepared.
But when the interviewer insisted, asking her for just one word to describe the same, her candid response was,
Uhmmm, no. [Laughs] I have enough secrets.
So that means we won’t be getting any answers about her character in this next Marvel movie, which is slated for a 2026 release anytime soon. But while that’s that, it hasn’t stopped fans from launching into speculation mode about the character she could potentially be playing – especially now that even set pictures have been leaked.
Fans Are Busy Speculating About Sadie Sink’s Brand New Day Character

In the leaked images, Sadie Sink sported red hair, which has since had fans speculating that she could be playing one of the many iconic redheads in the Marvel Universe. While some of them are speculating that she could be Mary Jane or Aunt May, others have even more diverse choices.
Meanwhile, some other fans are also joking about how straightforwardly the actress avoided the question about describing her character in one word during the interview, also comparing her to her co-star Tom Holland, who is practically known as the ‘King of Marvel Spoilers.’
Here’s what all these fans have to say on X:

Well, with all this out there, as intrigued as fans might be to know who exactly Sink will be embodying for Brand New Day, guess they’ll have to wait until official confirmation to get their answers. For now, they might as well let her focus on shooting and not spilling any spoilers!
Spider-Man: Brand New Day is currently scheduled to be released on July 31, 2026.
