Marvel Studios premiered the second trailer for Avengers: Doomsday during the D23 Expo, offering a direct look at Robert Downey Jr.’s Doctor Doom confronting the Marvel Cinematic Universe's primary roster.

Direction and Cast Lineup

Directed by Joe and Anthony Russo, the film features an extensive ensemble cast. The roster combines returning MCU veterans including Chris Evans, Chris Hemsworth, and Tom Hiddleston with the newly integrated Fantastic Four and the Thunderbolts. According to the footage screened at D23, the production also incorporates original 20th Century Fox X-Men franchise actors Patrick Stewart and Ian McKellen, establishing the scale of the multiversal collision.

Theatrical Release Schedule

The studio confirmed the film's theatrical release date for December 18, 2026, with a confirmed runtime of 165 minutes.

This second promotional rollout establishes the narrative bridge for the multiversal crossover event leading directly into Avengers: Secret Wars, anchoring Disney's late-year box office strategy.
