Doctor Doom’s Sentinel army takes centre stage in Doomsday trailer
Developed over time first seen 2 weeks ago
Marvel Studios surprised fans at San Diego Comic-Con with exclusive footage from "Avengers: Doomsday," giving a first proper look at Robert Downey Jr.'s turn as Victor Von Doom. The trailer, shown to those inside Hall H, frames Doom not simply as a villain but as a once-brilliant man broken by loss, with Vanessa Kirby's Sue Storm narrating his fall from "the smartest guy in the room" into a vengeful figure who tells the assembled heroes they have "lived stolen lives." The footage matters because it signals the tone and scale of Marvel's biggest crossover yet, merging previously separate franchises into a single confrontation.
The trailer intercuts glimpses of a sprawling cast, including Thor, Captain America, Black Panther, Shang-Chi, Loki, Cyclops, Magneto and Gambit, over shots of a devastated New York, before culminating in Doom effortlessly repelling Thor and summoning an army of Sentinel robots from the "X-Men" films. The film unites the Avengers, Fantastic Four, Thunderbolts and Fox's returning X-Men cast, featuring stars such as Chris Evans, Chris Hemsworth, Pedro Pascal, Patrick Stewart and Ian McKellen, and is scheduled for release on 18 December 2026 after a year of teaser trailers building anticipation.

New here? Start with this
Doctor Doom is a longstanding Marvel villain, a genius ruler driven by grief and grievance, and Robert Downey Jr — previously known for playing the hero Iron Man — is now taking on the role for the first time in Marvel's shared cinema universe. In the new footage, the character is shown turning from brilliant scientist to enemy of the heroes after suffering a personal loss, before unleashing an army of robotic Sentinels against them.
Avengers: Doomsday matters because it merges several separate strands of Marvel films and characters that have so far been kept apart, including the Avengers, the Fantastic Four, the X-Men and the Thunderbolts. It brings back familiar faces such as Chris Evans and Chris Hemsworth alongside newer additions like Pedro Pascal, and marks the on-screen return of established X-Men actors within this shared story world.
The film is due for release on 18 December 2026 and has been building anticipation through a series of trailers over the past year, of which this is the latest.
