The upcoming movie, Avengers: Doomsday, will bring together two Avengers teams – the group from Thunderbolts and Sam Wilson’s team – alongside the Fantastic Four (who first appeared in a 2025 film) and the X-Men. However, it won’t feature a brand new team of mutants. Instead, Doomsday will bring back many of the original X-Men film actors, including James Marsden, Patrick Stewart, and Ian McKellen. Kelsey Grammer, despite only appearing in one of the previous Fox films, is also returning and has hinted at who his character, Beast, will be interacting with.
