The Russo Brothers released a short clip that isn't the more substantial video that should be in theaters soon.

The Avengers Doomsday trailer has officially hit theaters and was leaked a few days prior as well and... Marvel Studios has confirmed that Steve Rogers, Captain America, is indeed returning for Avengers Doomsday.

Avatar: Fire and Ash arrives in theaters this weekend, and while the third instalment in James Cameron's block-busting sci-fi saga didn't need to give audiences any additional incentive to show up, the decision to debut the first teaser trailer for Marvel Studios' Avengers: Doomsday ahead of the movie certainly hasn't hurt anticipation.

Avengers: Doomsday is set to release on December 18, 2026. As shown by March's ultra-long livestream, the full cast is stacked. It includes legacy MCU actors, post-Endgame heroes, plus X-Men, Thunderbolts, and Fantastic Four actors.

Avengers: Doomsday is set to feature a ton of different new and returning stars to the MCU, including Chris Evans in a reported return to Captain America. While the news will excite most, it does also damage one of Marvel Studios’ biggest movies.
