Sadie Sink shares how she first heard about her involvement in Spider-Man: Brand New Day, with her character still shrouded in secrecy and fans speculating wildly.

Sadie Sink, best known for her role in Stranger Things, is set to join the cast of Spider-Man: Brand New Day, the fourth instalment in the Marvel Cinematic Universe’s web-slinging saga. Curiously, she didn’t learn about her casting from the studio itself. Instead, the news reached her through the digital grapevine, with online chatter tipping her off before any official word landed in her inbox.

Appearing on The Tonight Show with Jimmy Fallon, Sink recounted the rather unconventional way she discovered her involvement.

“I found out through online theories,”

she admitted, explaining that she stumbled across the speculation a full two days before Marvel Studios made things official.

“Before I got cast in Spider-Man, there was speculation online that said, 'Sadie Sink is gonna be in the new Spider-Man,' I was like, 'I am?' Sure enough, two days later, they asked me to do it! So yeah, those theories, there's sometimes some truth to it!”

Speculation Swirls Around Sink’s Mysterious Character

Details about Sink’s role remain tightly under wraps, fuelling a flurry of theories among fans and pundits alike. The rumour mill has churned out a handful of frontrunners, with some suggesting she could be stepping into the shoes of a reimagined Mary Jane Watson. Others have floated the idea of Rachel Cole, a character linked to the Punisher, or even a fresh take on Jean Grey from the X-Men universe.

Sink herself seems to be enjoying the guessing game, though she admits it’s not always easy to keep a lid on things.

“It's torture! There's so much speculation,”

she confessed, noting that the rumour machine never really slows down.

“I feel like there's a new character every week. I tell people, like the people I know.”

Fortunately, her inner circle has managed to keep the secret safe, at least for now.

Hints and Theories: Who Might She Play?

Among the various theories, Rachel Cole appears to be a popular pick, especially given the confirmed presence of Jon Bernthal’s Frank Castle in the upcoming film. Some eagle-eyed fans have even pointed to leaked set photos, which seem to show Sink sporting camouflage gear—a possible nod to Cole’s military background.

Of course, nothing has been confirmed, and Marvel’s notorious secrecy means audiences will likely be left guessing until the film’s release. The speculation, however, has only added to the anticipation, with each new rumour sparking fresh debate across social media and fan forums.

Countdown to Release

With Spider-Man: Brand New Day slated to arrive in cinemas on 31 July, excitement continues to build. In the meantime, fans can keep themselves occupied by tracking the latest developments from Marvel’s ever-expanding slate of films and series, all while trying to piece together the puzzle of Sink’s mysterious role.
