Avengers: Doomsday and Secret Wars Delayed to December

Marvel's Multiverse Saga Faces Major Shake-Up

Marvel Studios has announced a significant reshuffling of its release calendar, pushing back the highly anticipated “Avengers: Doomsday” and “Avengers: Secret Wars” to December 2026 and December 2027, respectively. Originally slated for summer releases, the films are now positioned in the holiday corridor, a move that reflects the studio's strategic planning and the ambitious scale of these projects.

“Avengers: Doomsday,” initially set for May 1, 2026, will now premiere on December 18, 2026. Its sequel, “Avengers: Secret Wars,” moves from May 7, 2027, to December 17, 2027. The delays are not indicative of behind-the-scenes issues but rather underscore the complexity and magnitude of the narratives being crafted. Both films are directed by the Russo Brothers, known for their work on “Avengers: Infinity War” and “Avengers: Endgame.”

The decision to shift to December releases isn't unprecedented. Marvel has previously found success in this window, notably with “Spider-Man: No Way Home.” The holiday season offers a lucrative box office period, and the studio aims to capitalize on this timing.

Production on “Avengers: Doomsday” is already underway at Pinewood Studios in England. Despite the commencement of filming, the script and cast are still being finalized, as Marvel continues to coordinate the involvement of various actors across its expansive universe. The film is expected to feature a massive ensemble cast, including characters from previous Avengers and Marvel movies, the X-Men, and the Fantastic Four. Notably, Robert Downey Jr. is set to return, not as Iron Man, but portraying the villain Doctor Doom—a role reports suggest Marvel spent heavily to secure.

The release date for “Avengers: Doomsday” now coincides with that of “Dune: Messiah,” setting the stage for a potential box office showdown. However, industry insiders speculate that one of the films may shift dates to avoid direct competition.

In the interim, Marvel fans can look forward to other Phase Six releases, including “The Fantastic Four: First Steps” on July 25, 2025, and “Spider-Man: Brand New Day” on July 31, 2026. These films are expected to lay the groundwork for the events of “Avengers: Doomsday” and “Avengers: Secret Wars.”
