Star of the Netflix series for many years, Sadie Sink is exploding in Hollywood. She will even be one of the new faces of the Marvel Universe.

At 23, she began to make a name for herself in Hollywood.

Sadie Sink continues her meteoric trajectory. After her arrival in the Marvel Universe via Spider-Man: Brand New Day, currently filming, the Stranger Things actress should continue the MCU adventure. She will also be in the cast of Avengers: Secret Wars, if we are to believe information from the very serious Deadline, but which neither Marvel Studios nor the actress have confirmed for the moment.

Sink was announced in March 2025 in Spider-Man 4 alongside Tom Holland, Zendaya and Jacob Batalon. According to Deadline:

“Spider-Man: Brand New Day is due out on July 31. There’s a lot of speculation about Sink’s role in the film and, frankly, I don’t have the answer. But I do know that she will join the next Avengers film, which will shoot in London in late 2026.”

Given her red hair, it is rumored that the actress could play Mary-Jane Watson, and take over from Kirsten Dunst. But the secret of her role is well kept, which fuels speculation: Jean Grey, Mayday Parker, Gwen Stacy, even Rachel Cole, partner of the Punisher version Jon Bernthal… nothing is confirmed, but each new set photo restarts the theory machine.

Her presence in Secret Wars in any case suggests that she will play an important character in Marvel lore. Filming is scheduled for summer 2026.

For now, Sadie Sink is finishing filming Spider-Man, scheduled until mid-December

Spider-Man: Brand New Day will be released in theaters on July 29, 2026. As for Avengers: Secret Wars, the release is scheduled for December 2027.
