The star of \"Stranger Things\" will appear not only in \"Spider-Man: A New Day\".
Actress Sadie Sink, who is involved in the film \"Spider-Man: A New Day\", will also appear in the next part of the Marvel Cinematic Universe. According to Deadline, Sink will join the cast of \"Avengers: Secret Wars.\"
This information appeared in the Breaking Baz column, which journalist Baz Bamigboye dedicated to Sink's theatrical debut in the production of \"Romeo and Juliet\" on the London stage.
\"I know she is joining the cast of the next Avengers movie, which will be filmed here in London in late 2026.\"
Although Baz did not directly name \"Secret Wars,\" the mention of filming in late 2026 excludes her participation in \"Avengers: Judgment Day,\" the main filming part of which has already been completed, and the release is scheduled for December 18, 2026.
\"Secret Wars\" should complete the sixth phase of the Marvel Cinematic Universe, the so-called \"multiverse saga,\" which means that the seventh phase and a new cycle will begin after them until the next crossover. It follows that the only Avengers movie in which Sink could star at the end of next year is \"Secret Wars.\"
The role that the actress will play remains a mystery. Despite the fact that filming of \"Spider-Man: A New Day\" is in full swing, even Sink's photos from the set do not give an exact answer as to who she is playing.
At the moment, she is credited with several options: Mayday Parker — Peter Parker's daughter from an alternate universe; Beetle — Tombstone's daughter, who will appear in the film played by Marvin Jones III; or an alternate version of Mary Jane. Fans also recall old rumors about Sink being cast as Jean Grey, but sources close to the project do not confirm them.
Marvel is likely to hide the actress's role until the very last moment, as is often the case with key characters in major crossovers. More information is likely to appear closer to the premiere of the film \"Spider-Man: A New Day,\" scheduled for July 30, 2026.
