Marvel Studios releases Avengers Doomsday trailer, Dec 18

Marvel Studios has unveiled the first full trailer for its upcoming crossover event "Avengers: Doomsday," setting the stage for a multiversal conflict that will unite heroes from across the Marvel Cinematic Universe, the Fantastic Four, and the X-Men. The trailer, released on July 20, 2026, confirms the film will hit theaters on December 18, 2026, and introduces Robert Downey Jr. as the formidable villain Doctor Doom.

Directed by Joe and Anthony Russo, the film appears to adapt elements of the major comic storyline "Time Runs Out," focusing on a crisis of incursions where parallel Earths collide, threatening entire universes with destruction. The two-and-a-half-minute trailer opens on a devastated Xavier's School for Gifted Youngsters, with an ominous voiceover from Doom warning of an unstoppable threat and an "unthinkable decision." Scenes depict widespread chaos at the X-Mansion, with characters like Professor X and Magneto witnessing an attack and heroes from different realities, including Gambit, Shang-Chi, Yelena Belova, and Mystique, engaged in combat.
