Marvel Studios premiered a two-minute trailer for Avengers: Doomsday at Disney's D23 fan convention on August 14, revealing Doctor Doom raising an army of Sentinels and showcasing his great power by easily swatting Thor aside [1, 2, 3]. The trailer also highlights the Fantastic Four, with Reed Richards and Sue Storm reacting to the threat Doom poses. Sue Storm tearfully says "Doom is broken," suggesting Doom is driven by revenge after losing close family members [1, 2, 3].
Robert Downey Jr. plays Doctor Doom, who leads this destructive assault, leaving a ruined city behind and prompting Reed Richards to confront him about the devastation shown in the trailer [2]. The casting features a broad roster of returning Marvel stars from both the MCU and Fox X-Men films—including Chris Hemsworth, Anthony Mackie, Sebastian Stan, Letitia Wright, Paul Rudd, Tom Hiddleston, Patrick Stewart, Ian McKellen, Rebecca Romijn, and others [1].
Chris Evans, returning as Captain America after seven years, said the movie will be brutal for Steve Rogers. He quoted, "The Russos love beating up Steve Rogers. Their favorite thing to do is to just beat the crap out of him. To them that's what makes a hero, and that's someone who gets punched so many times but still gets up" [2].
Avengers: Doomsday is scheduled for theatrical release on December 18, 2026 [3]. The film’s events will lead directly into Avengers: Secret Wars, set to debut on December 17, 2027 [3].
