Sadie Sink Found Out About Her ‘Spider-Man’ Casting Via Online Speculation: “There’s Sometimes Some Truth To It”

Although sworn to secrecy by the MCU, Sadie Sink admits there’s sometimes some truth to the online fan theories.

The actress, who will star in Spider-Man: Brand New Day in an undisclosed role, admitted “it’s torture” not being able to tell people which character she’s playing in the fourth installment of the Marvel Studios franchise.

“There’s so much speculation too, I feel like there’s a new character every week,” she said The Tonight Show Starring Jimmy Fallon.

“I tell people, like the people I know,” added Sink. “But I found out through online theories. There was speculation online that said, ‘Sadie Sink is going to be in the new Spider-Man.’ I was like, ‘Hmm? I am?’ And sure enough, two days later, they asked me to do it. So yeah, those theories, there’s sometimes some truth to it.”

Although many have speculated that Sink will play fellow redhead Mary Jane Watson, the Stranger Things alum previously played coy about the theory. “A lot of people forget that hair color can change, but yeah, I understand all of the theories,” she told Entertainment Weekly.

Deadline reported in March that Sink was set to star in the upcoming Spidey pic. Additionally, Liza Colón-Zayas joins the cast in an undisclosed role.

After filming began in Glasgow, Scotland in August, Spider-Man: Brand New Day director Destin Daniel Cretton announced last month that filming wrapped, ahead of the scheduled July 31 premiere date.
