Marvel has released a new Avengers: Doomsday promotional film that mixes Major League Baseball stars with fresh glimpses of the Avengers reassembling ahead of the film’s 18 December 2026 cinema release.

The official Marvel Japan announcement, dated 29 October, is more than a sports crossover. Alongside a stadium sequence built around Mister Fantastic throwing a spectacular ceremonial first pitch, it includes previously unseen shots of Steve Rogers meeting Thor again, Ant-Man and Sam Wilson’s Captain America joining the line-up, and Doctor Doom interrupting the celebration.

What is in the new Avengers: Doomsday footage?

The spot opens in a baseball stadium as Reed Richards is announced for the ceremonial first pitch. MLB players Freddie Freeman, Bryce Harper, Randy Arozarena, Jacob Misiorowski and Junior Caminero appear in the film, reacting as Mister Fantastic uses his elastic powers to turn a familiar pre-game ritual into a superhero set-piece.

The tone changes when Doctor Doom arrives. Marvel’s release says the video also contains first-look material of Steve Rogers and Thor together again, plus a broader Avengers assembly preparing for the threat ahead.

That makes the clip useful to fans beyond its baseball hook: it is a compact preview of how the film is bringing together several generations of MCU heroes while positioning Robert Downey Jr.’s Doctor Doom as the new central danger.

When is Avengers: Doomsday released?

Marvel Japan lists Avengers: Doomsday for 18 December 2026. UK cinema listings and exact showtimes can vary by chain, so fans should check local booking pages as the date approaches rather than relying on overseas promotion times.

The official announcement describes the film as the first Avengers feature in seven years and a continuation beyond Avengers: Endgame. It also confirms Robert Downey Jr. as Doctor Doom and frames the story around the Avengers confronting a threat capable of ending their world.

Why this clip matters to collectors and convention fans

Every new line-up reveal tends to shape the next wave of posters, figures, cosplay builds and convention discussion. Steve Rogers and Thor sharing the screen again is the headline moment, but the mixture of Mister Fantastic, Sam Wilson, Ant-Man and Doctor Doom gives collectors several costume and character details to examine.
