[UPDATE] Marvel Announcement Video Reveals Avengers: Doomsday Cast, X-Men confirmed

Marvel has started a surprise livestream that is announcing the cast of Avengers: Doomsday.

The video is revealing various MCU actor names, displayed on the back of a series of chairs, alongside their character's musical themes.

Names shown so far include Chris Hemsworth (Thor), Vanessa Kirby (Invisible Woman), Anthony Mackie (Captain America), Sebastian Stan (Winter Solder), Letitia Wright (Shuri / Black Panther), Paul Rudd (Ant-Man), Wyatt Russell (John Walker / U.S. Agent), Tenoch Huerta Mejía (Namor), Ebon Moss-Bachrach (The Thing), Simu Liu (Shang-Chi), and Florence Pugh (Yelena Belova).

Kelsey Grammer is also now confirmed to appear in Avengers: Doomsday, confirming the X-Men are in the film. Grammer famously played Beast in the Fox X-Men films and made his MCU debut via The Marvels.

Late last year, MCU cheif Kevin Feige teased the introduction of X-Men characters in the "next few" MCU movies. Feige told an audience at the Disney APAC Content Showcase in Singapore that fans would see “some X-Men players that you might recognize” in the next few MCU movies, but he stopped short of saying which characters or what movies.

On bringing the X-Men into the MCU, Feige added: “I think you will see that continues in our next few movies with some X-Men players that you might recognize.

“Right after that, the whole story of Secret Wars really leads us into a new age of mutants and of the X-Men. Again, [it’s] one of those dreams come true. We finally have the X-Men back.”

Feige has also said the X-Men will be an important part of the MCU’s future following Secret Wars. "When we were preparing for Avengers: Endgame years ago, it was a question of getting to the grand finale of our narrative, and then we had to start all over again after that,” Feige said. “This time, on the road to Secret Wars, we already know very well what the story is going to be until then and afterwards. The X-Men are an important part of that future.”

Earlier this month, the Russo brothers said they see Avengers 5 and 6 as a “new beginning” that will lay the foundation for whatever comes next in Phase 7 of the MCU.

“The only thing I’ll say about the movie is this: we love villains who think they’re the heroes of their own stories,” Joe Russo said. “That’s when they become three-dimensional and they become more interesting. When you have an actor like Robert Downey, you have to create a three-dimensional, well shaped character for the audience. That’s where a lot of our focus is going.”

Avengers: Doomsday is currently set to arrive in theaters May 1, 2026 and Secret Wars arrives about a year later in May 2027. Thunderbolts* comes out in May 2025, TV show Ironheart is out in June, and Phase 6 kicks off with The Fantastic Four: First Steps in July.

In October, Marvel Studios added three untitled movie projects to its 2028 release schedule: February 18, 2028; May 5, 2028; and November 10, 2028. It seems increasingly likely one of these movies is X-Men.
