Many actors affiliated with past Marvel projects—including Brie Larson, Famke Janssen, Elizabeth Olsen, Charlie Cox, Andrew Garfield, Halle Berry, and Chris Evans—have either remained silent or denied reprising their roles in this film.
Notable Commentary
Channing Tatum, returning as Gambit, said Avengers: Doomsday will contain moments “50 times bigger than when Wesley Snipes' Blade appeared in Deadpool & Wolverine.”
Summary: The Avengers: Doomsday trailer is set to premiere with Avatar: Fire and Ash in December 2025, promising an epic crossover of Marvel's most iconic teams despite limited plot details.
