The first footage from Avengers: Doomsday is set to debut surprisingly early. According to Collider, a trailer for Avengers: Doomsday will be shown before screenings of Avatar: Fire and Ash.
James Cameron's threequel, introducing Pandora's Ash People, is scheduled to hit cinemas on December 19, 2025. This means the first look at Avengers: Doomsday will arrive almost exactly one year before its own release, which is set for December 18, 2026.
This 12-month lead suggests Marvel Studios may be very confident in Doomsday, potentially sparking extensive speculation about the movie, which has largely remained a mystery.
Robert Downey Jr. is confirmed to return. In addition, the casts of Fantastic Four and Thunderbolts will join several MCU heroes and legacy X-Men characters. The full cast list was revealed during a six-hour livestream in March.
Recently, Gambit actor Channing Tatum said Avengers: Doomsday "could be the biggest film of the decade."
Marvel's early trailer release for Avengers: Doomsday ahead of Avatar: Fire and Ash signals strong confidence and fuels excitement for a major MCU event in 2026.
