The X-Men are officially crashing the Marvel Cinematic Universe party in a massive way. Kelsey Grammer just dropped a huge bombshell regarding his return as the intellectual blue mutant, Hank McCoy. His recent comments confirm he will join the fight in Avengers: Doomsday alongside some of the biggest names in Hollywood history.
This is the moment comic book fans have waited years to see on the big screen. Grammer previously teased audiences with a shocking cameo at the end of The Marvels back in 2023. Now he is making it clear that appearance was just the start of a much larger role.
A Mutant Reunion on the Big Screen
Kelsey Grammer is not just stopping by for a cup of coffee this time around. Speaking in a recent interview with Entertainment Tonight, the legendary actor opened up about stepping back into the blue fur. He expressed genuine joy about revisiting the character of Beast after so many years away from the franchise.
He made it clear that this experience felt like a fresh adventure compared to his previous X-Men outings. The actor hinted at significant screen time rather than a blink and you miss it moment.

“To come back as Beast was fun. I do not know how much I am allowed to talk about. But it was fun to interact with people I had not acted with before.”
This statement suggests that Beast will be a central figure in the plot. He is not just standing in the background. He is actively working with other heroes to solve the crisis at hand.
The film is shaping up to be a massive gathering of legacy actors. Reports indicate Grammer joins a cast that honors the history of Marvel movies.
Returning X-Men Legends:
- Patrick Stewart as the telepathic leader Professor X.
- Ian McKellen returning as the master of magnetism Magneto.
- Rebecca Romijn donning the blue makeup again as Mystique.
- James Marsden back with his laser visor as Cyclops.
- Alan Cumming making a rare return as the teleporter Nightcrawler.
This lineup confirms the movie explores the multiverse concept deeply. Worlds are colliding. The original X-Men team is meeting the current Avengers roster.
Interacting with Thor and Fantastic Four
The most exciting part of the interview came when Grammer discussed his new co-stars. He specifically mentioned sharing scenes with characters we have never seen Beast interact with before. This is the crossover magic that drives the Marvel Cinematic Universe forward.
When asked who thrilled him the most, Grammer gave a surprising answer. He shouted out the God of Thunder himself.
“You know, Thor. I am a big fan.”
This confirms that Hank McCoy and Thor will share the screen. Imagine the scientific mind of Beast trying to understand the magical powers of an Asgardian god. It creates a dynamic that is both funny and fascinating for the audience.
Grammer also let a major detail slip regarding the Fantastic Four. He confirmed he shot a sequence with “Pedro.” This refers to Pedro Pascal, who is playing Reed Richards, also known as Mister Fantastic.
Why this interaction matters:
- Battle of the Brains: Both Beast and Reed Richards are super geniuses.
- Illuminati Potential: In the comics, these men belong to a secret group that runs the world.
- Science Bros: They likely work together to stop the multiversal collapse.
Seeing these intellectual heavyweights together is a dream come true. They are likely the ones trying to solve the “Doomsday” problem while the other heroes fight the physical battles.
Robert Downey Jr and the Doom Factor
The biggest shadow hanging over this movie is the return of Robert Downey Jr. He is not playing Iron Man this time. He is playing the villain, Doctor Doom. Grammer expressed his deep admiration for Downey during his chat.
“I am a big fan of Robert Downey Jr. I love him.”
This comment carries a lot of weight. If Beast is interacting with Thor and Reed Richards, he is almost certainly crossing paths with Doctor Doom.
The stakes in this movie are incredibly high. Doctor Doom is a threat to the entire multiverse. The Avengers need help from every timeline to stop him. That is where the X-Men come in.
Beast brings a unique perspective to this fight. He is a diplomat and a scientist. He might try to reason with Doom before the fighting starts. Or perhaps he helps build the technology needed to defeat him.
Key Character Dynamics:
| Character | Relationship with Beast | Expected Interaction |
|---|---|---|
| Thor | Ally | Comedy and Power display |
| Mr. Fantastic | Scientific Peer | Solving complex physics problems |
| Doctor Doom | Enemy | Intellectual rivalry and conflict |
Grammer seems energized by the talent around him. His excitement is contagious. It tells us that the script gave him something substantial to do. He is not just there for nostalgia. He plays a key part in the story.
What This Means for the Marvel Universe
The inclusion of Kelsey Grammer as Beast signals a permanent shift for Marvel. The era of keeping mutants separate from the Avengers is over. Disney acquired the rights to X-Men years ago. We are finally seeing the payoff.
The Marvels post-credit scene showed Beast monitoring a confused Monica Rambeau. He was in a high-tech lab in a parallel universe. This new movie likely picks up right where that scene left off.
The Narrative Path:
- Monica Rambeau is stuck in Beast’s universe.
- An incursions event begins, threatening to destroy both worlds.
- Beast and the X-Men must travel to the main MCU timeline (Earth-616).
- They team up with Thor and the Fantastic Four to save reality.
This storyline aligns perfectly with the “Secret Wars” comic book runs. It allows for endless cameos and team-ups. But Grammer’s confirmation proves these aren’t just quick cameos. These are supporting roles with dialogue and impact.
Fans should prepare for an emotional ride. Seeing these classic actors return might be the last time they play these roles. It is a celebration of twenty years of superhero cinema.
Grammer clearly enjoyed the process. His willingness to speak so openly suggests he is proud of the work. It also suggests Marvel is loosening the leash on spoilers just a little bit to build hype.
We are looking at a December 2026 release window for this massive event. The long wait gives the studio time to perfect the visual effects. A character like Beast requires top-tier CGI to look realistic next to real actors.
Kelsey Grammer returning as Beast is a massive win for moviegoers. It bridges the gap between the old generation of mutant movies and the modern Avengers era. His scenes with Thor and Mister Fantastic promise to be the highlight of the film. The excitement in his voice is real. If the actor is this hyped, the fans are in for something truly special. Get ready to see the blue furball use his brains and brawn to save the multiverse.
