Avengers: Doomsday arrives in theaters on December 18, 2026, which is about six weeks away. Directors Anthony and Joe Russo return to the MCU for the film, and Robert Downey Jr. plays the villain, Doctor Doom. Because the movie brings the Avengers, the Fantastic Four, the X-Men and the Wakandans together, it’s one of the year’s biggest releases. Below, you’ll find the release date, the cast, the trailers and what to expect.
Avengers: Doomsday release date
Avengers: Doomsday opens exclusively in theaters on December 18, 2026 in the US, and tickets are already on sale. In some countries, it opens a few days earlier. For example, listings show December 16 or 17 in several markets, so check your local cinema.
The film moved around a bit before it settled on this date. Earlier, Marvel planned a May 2026 release. Since then, though, the film has stayed on schedule, which is unusual for a blockbuster this size.

Avengers: Doomsday trailers
Marvel has released several previews so far:
- January 2026: four teasers, showing the return of Steve Rogers and Thor, plus the debut of the X-Men.
- July 20, 2026: the first full trailer.
- August 15, 2026: a “special look” at Disney’s D23 event.
According to Deadline, the full trailer shows Chris Evans returning as Steve Rogers for the first time since Avengers: Endgame. It also features Shang-Chi, Yelena Belova, the Thunderbolts, Namor, Gambit, the Fantastic Four and Magneto, among others.
What is Avengers: Doomsday about?
Marvel hasn’t shared a detailed plot, so the story stays under wraps. However, we know the basics. Disney says the film brings the Avengers, the Fantastic Four, the X-Men and the Wakandans together as Robert Downey Jr. plays Doctor Doom. In other words, major Marvel teams from across the multiverse must fight a single threat.
Meanwhile, the Russo brothers say Thor returns to the warrior mindset of Avengers: Infinity War. As a result, fans expect a darker, more intense story than recent MCU films.
Avengers: Doomsday cast
The cast is huge, and Marvel hasn’t confirmed every appearance. Here are some of the names reported so far:
Robert Downey Jr. as Victor von Doom / Doctor Doom
Chris Hemsworth as Thor
Chris Evans as Steve Rogers
Tom Hiddleston as Loki
Paul Rudd as Scott Lang / Ant-Man
Anthony Mackie as Sam Wilson / Captain America
Sebastian Stan as Bucky Barnes
Florence Pugh as Yelena Belova
Letitia Wright as Shuri
Pedro Pascal, Vanessa Kirby, Joseph Quinn and Ebon Moss-Bachrach as the Fantastic Four
Patrick Stewart as Professor X
Ian McKellen as Magneto
Why does Doctor Doom matter?
The Russo brothers’ last Avengers film was Endgame in 2019. Since then, Marvel has moved away from Kang, who was originally the villain of this story, back when the film was called The Kang Dynasty. Therefore, Doctor Doom now takes center stage. Fans first saw him briefly in The Fantastic Four: First Steps. Overall, the four Avengers films so far have earned more than $7.7 billion at the box office, so expectations are high.
Where to watch Avengers: Doomsday
The film opens exclusively in theaters on December 18, 2026. Disney says it will come to Disney+ later, but it hasn’t announced a date. In the meantime, you can book tickets now, and some premium formats like ScreenX are listed too.
Do you need to watch other Marvel movies first?
It helps, but you don’t need to watch everything. Because the film continues the story of the Avengers and brings back characters from several different eras, the best preparation is Avengers: Endgame, Thunderbolts, Black Panther: Wakanda Forever and The Fantastic Four: First Steps. If you have less time, a quick recap of the main characters is enough.
