Well, we didn't see that coming.

Thanks to Marvel Studio's livestream reveal of the Avengers: Doomsday cast, we are thrilled to report that Kelsey Grammer will be returning to the Marvel Cinematic Universe for the MCU's next event film.

Garmmer's last appearance in the MCU was in The Marvels, during which their character Hank McCoy was revealed to be part of an adjacent universe. We should clarify here, though, that it is uncertain whether Grammer will be returning as Beast. Robert Downey Jr.'s casting as Victor Von Doom after spending over a decade playing Tony Stark/Iron Man should cast all such assumptions into doubt.

Hopefully, we'll know the exact details of Kelsey Grammer's return soon. You can bet that as soon as we do, we'll tell you.

Avengers: Doomsday is coming to theaters May 1, 2026.
