If there’s one thing Marvel fans know, it’s that the MCU has a thing for keeping things secret. So, when Marvel dropped its big Avengers: Doomsday casting announcement on March 26, 2025, with a five-hour livestream that racked up a mind-blowing 275 million views, it was clear something huge was coming. But the first reaction from the cast? Paul Rudd, of course. The actor who made Ant-Man a household name had some thoughts—especially about that tiny chair. Why did they have to make Paul Rudd’s chair so tiny in the Avengers: Doomsday cast reveal?
During a fun appearance on Jimmy Fallon, Rudd, ever the good sport, joked about the “Ant-Man-sized” seat featured in the announcement. “I saw that announcement. I did. I thought, ‘Oh that’s clever, yes I’m Ant-Man.’ But there’s still the part of me that’s like, it’s a little emasculating to have a little tiny chair. But at least, finally, one that will actually fit me when I sit down.” Classic Rudd. You can almost hear the chuckles of every fan who’s wondered if that chair was really necessary.

Of course, Rudd wasn’t spilling any Avengers: Doomsday secrets. Marvel’s notorious for its tight-lipped policy, especially when it comes to spoilers. “There is nothing that I can tell you,” Rudd quipped. “They are really secretive. It’s important… Clearly, as we know, they never announce anything. This is—You know, it’s a major movie. You can’t be frivolous with this kind of stuff. It’s nothing like, you know, military secrets or anything. This is a major motion picture. This is not something you put in a group chat.” Cough Tom Holland cough. But hey, when you’re trying to avoid becoming the next leak machine, Rudd’s got the right idea.
Marvel’s March livestream revealed 27 actors, including a few names we never saw coming. The big surprise? A whole lot of familiar faces from the Fox X-Men franchise. Yup, Kelsey Grammer (Beast), Patrick Stewart (Professor X), Ian McKellen (Magneto), Rebecca Romijn (Mystique), and James Marsden (Cyclops) are all back. Oh, and Channing Tatum, who’s back as Gambit after his brief Deadpool & Wolverine stint. Even Robert Downey Jr. is returning—this time, as Doctor Doom. If you didn’t have chills yet, now’s the time to start wondering: Is Avengers: Doomsday secretly an Avengers vs. X-Men movie?
With the Russo Brothers back to direct and a cast that’s shaping up to be one of the biggest in MCU history, we know one thing for sure: Avengers: Doomsday is going to be a game-changer. The movie drops on May 1, 2026, but fans are already going wild over what this could mean for the future of the MCU—and X-Men. Whether this is the big crossover we’ve been waiting for, or just a tease to leave us guessing, one thing’s for certain: Doomsday can’t come soon enough.
