When you think about the smartest mutant in the mansion, your brain probably goes straight to a blue, furry guy in a lab coat reading Shakespeare. Most fans immediately picture Kelsey Grammer. Or maybe they see Nicholas Hoult. It really depends on when you started watching the movies. The beast x men actor legacy is actually more crowded than you might remember, and it’s about to get even bigger with the MCU officially knocking on the door.
Honestly, it's kinda wild how many people forget the very first time we saw Hank McCoy on screen.
The Cameo Everyone Forgets
Before the fur. Before the politics. Before the serum. In X2: X-Men United, there’s a tiny blink-and-you’ll-miss-it moment on a television screen. Steve Bacic—a guy you might recognize from Stargate SG-1—played a human version of Dr. Hank McCoy during a news interview. He didn't have claws. He wasn't blue. He was just a smart guy in a suit.
Most people skip right over this because, let’s be real, we wanted the Beast. We wanted the acrobatic genius. But Bacic holds the title of being the first live-action version, even if he never got to put on the prosthetics.
Kelsey Grammer: The Definitive "Old Man" Beast
When X-Men: The Last Stand hit theaters in 2006, the casting of Kelsey Grammer was basically a stroke of genius. Think about it. He spent years playing Frasier Crane, a man defined by his intellect and upper-crust vocabulary. Transitioning that energy into Hank McCoy felt natural.

Grammer didn't just play a monster; he played a diplomat. He brought a sense of "dignity and decency" to the role that resonated with fans of the original comics. He’s gone on record comparing Beast to a civil rights figure like Martin Luther King Jr., focusing on the character's heart rather than just his muscles.
"I've always thought of him as the Martin Luther King Jr. of the mutant community... it's his character that he relies on—his dignity and his kindness." — Kelsey Grammer.
The makeup process back then was a nightmare. We're talking four to five hours in a chair every morning. Glue, fur, prosthetics—the works. It’s no wonder he was a bit relieved when Marvel Studios called him back for The Marvels post-credits scene in 2023 and told him he could do it via performance capture this time.
Nicholas Hoult and the Prequel Era
Then the timeline reset. Or went back. Or whatever happened in First Class. Suddenly, we had Nicholas Hoult taking over the mantle. Hoult had a huge task: he had to show us a Hank McCoy who was insecure, awkward, and literally trying to "cure" his own feet.
Hoult’s version was much more of a "mad scientist" type. He built the Blackbird. He built the Cerebro prototype. But here’s a fun fact: Hoult actually modeled his performance on David Hyde Pierce’s Niles Crane from Frasier. He was literally imitating the TV brother of the original beast x men actor.

The evolution of his look was... controversial. In First Class, the makeup looked a bit more feline. Some fans called it "Kitten Beast." By Days of Future Past, they refined it, making him look more like the classic simian version. Hoult played the character across four main films:
- X-Men: First Class
- X-Men: Days of Future Past
- X-Men: Apocalypse
- X-Men: Dark Phoenix
He even did a tiny, uncredited gag cameo in Deadpool 2 where the younger X-Men are seen briefly behind a sliding door.
Why Beast Still Matters in 2026
The conversation around who plays the best Beast is heating up again because of Avengers: Doomsday. It's 2026, and we know for a fact that Kelsey Grammer is back in the mix. But this isn't just a nostalgia trip. The way Beast is being handled now—especially with the MCU crossover—shows that the character is the bridge between the old Fox universe and the new Disney reality.
There’s a complexity to Hank McCoy that most superheroes lack. He hates what he looks like but loves what he can do. He's a walking contradiction. Whether it's Hoult's youthful energy or Grammer's seasoned authority, the beast x men actor has to balance the animal with the academic.
What's Next for the Blue Furry Genius?
If you're looking to catch up on the Beast's journey, here is how you should actually approach it. Don't just watch the movies in order. Look at the specific performances.

- Watch X-Men: The Last Stand strictly to see Grammer’s physical performance. Ignore the plot if you have to, just watch how he moves.
- Check out X-Men: First Class for the internal struggle of a young man who just wants to fit in.
- Re-watch the post-credits of The Marvels to see the new CGI design that’s likely sticking around for the next few years.
The most important thing to remember is that we haven't seen the "final" version of Beast yet. With the Multiverse being what it is, we might even see both actors on screen together eventually. Stranger things have happened in the MCU.
If you want to keep tabs on the latest casting news for the upcoming X-Men reboot, keep an eye on official Marvel production leaks. There are already rumors of new actors being tested for a younger MCU-native Beast, but for now, the blue throne still belongs to the legends who built it.
