Marvel is making a big spectacle of announcing the full cast of the next Avengers movie live on YouTube and social media. Most of the names are predictable: Chris Hemsworth, Anthony Mackie, Florence Pugh, Paul Rudd, and various stars of Marvel’s upcoming The Fantastic Four: First Steps. But one name is definitely a surprise: Kelsey Grammer who has to be playing some version the X-Men character Beast.

Grammer first played Beast in the Fox film X-Men: The Last Stand way back in 2006. He then reprised the role (in CGI form, rather than the prosthetic makeup he wore in The Last Stand) two years ago in a brief post-credits cameo in The Marvels.
It feels safe to assume this is the version of the character Grammer will play in Avengers: Doomsday. And if this Beast is in the film, it would be shocking if there weren’t at least a couple more X-Men characters joining him.
Marvel acquired the rights to make X-Men movies when it purchased the 20th Century Fox film studio a few years ago. To date, they have made just one X-Men-centric film: Last summer’s Deadpool & Wolverine. They have also included a few other teases and hints about the X-Men in other films and shows, like Patrick Stewart’s cameo in Doctor Strange in the Multiverse of Madness and an allusion to mutants in Ms. Marvel.
As to which other X-Men may join Grammer, that remains to be seen. So far the confirmed stars of Avengers: Doomsday include Chris Hemsworth as Thor, Vanessa Kirby as the new Invisible Woman from the upcoming The Fantastic Four: First Steps, Anthony Mackie as Captain America, Sebastian Stan as Winter Soldier, Letitia Wright as the Black Panther, Shuri, Paul Rudd as Ant-Man, Wyatt Russell as U.S. Agent, Tenoch Huerta Mejia as Namor, Ebon Moss-Bachrach as the Thing, Simu Liu as Shang-Chi, and Florence Pugh as Black Widow.
Avengers: Doomsday is scheduled to open in theaters on May 1, 2026. The film is now officially in production. You can follow along with the continuing cast announcements below.
