Russo Brothers X-Men Avengers Doomsday Explanation

The Russo Brothers broke down why fan-favorite X-Men aren't showing up in Avengers: Doomsday, despite Marvel Studios finally having the Fox properties back in their pocket. Patrick Stewart's Professor X already got a cameo in Doctor Strange in the Multiverse of Madness as an Illuminati variant, with Kelsey Grammer's Beast also appearing, but the broader mutant roster remains conspicuously absent from the Avengers storyline. The filmmakers' reasoning likely centers on pacing, narrative focus, and not overcrowding what's already become a pretty massive ensemble. It's the classic problem of too many characters and not enough screen time to do them justice.
