While Marvel's official 2025 cast list left them out, three legacy names are dominating the Avengers: Doomsday rumor mill. Since these details stem from scoopers rather than the studio, they remain unconfirmed.
Insiders Daniel Richtman and Alex Perez report that Tobey Maguire will return as Spider-Man, reportedly filming separately in a motion-capture suit to maintain secrecy. Multiple leaks suggest the film could open with Maguire’s Spider-Man facing off against Hugh Jackman’s Wolverine as their universes collide. Additionally, scooper MyTimeToShineHello claims Willem Dafoe is in talks to return as Norman Osborn (Green Goblin).
However, contradictory reports suggest these legacy heroes could die early on. Marvel is famous for guarding secrets, so fans should expect clarity at San Diego Comic-Con (July 23–26, 2026) ahead of the film's theatrical release on December 18, 2026.
