This unexpected casting has sparked excitement and speculation about the film’s storyline and its potential connection to the X-Men. But what does Grammer’s return mean for the future of the MCU? Let’s dive into everything we know so far.

The Return of Kelsey Grammer as Beast
Why This Comeback is a Big Deal
- Grammer last portrayed Beast in “X-Men: The Last Stand” (2006), a role later taken over by Nicholas Hoult.
- His return suggests a deeper integration of the X-Men into the MCU, possibly paving the way for the long-anticipated mutant storyline.
- With the multiverse concept in full swing, Grammer’s older version of Beast could coexist with a younger iteration.
Marvel’s Strategy: Nostalgia Meets New Beginnings
Marvel Studios has been leaning into fan-favorite characters to boost excitement for its new phases. Grammer’s return follows similar nostalgic comebacks, such as Patrick Stewart’s Professor X in “Doctor Strange in the Multiverse of Madness” and Hugh Jackman’s Wolverine in the upcoming “Deadpool & Wolverine.”

How Will Beast Fit Into “Avengers: Doomsday”?

Possible Storyline Connections
- Multiversal Chaos – With “Doctor Strange in the Multiverse of Madness” cracking open the multiverse, Beast’s return could be linked to a timeline where the X-Men are already established.
- A New Avengers Team? – With many of the original Avengers retired or gone, could Beast be part of a fresh lineup alongside Shang-Chi, Captain America (Sam Wilson), and others?
- Ties to Mutantkind – Given Disney’s acquisition of 20th Century Fox, Marvel has the green light to introduce mutants into the MCU officially. Beast’s appearance could set the stage for the X-Men’s integration into future films.
Is This the Beginning of the MCU’s X-Men Era?
Marvel’s Long-Awaited X-Men Plans
Fans have been eager for the X-Men to join the MCU, and Beast’s return could be the first major step. Kevin Feige has hinted at the X-Men’s introduction, and “Avengers: Doomsday” might be the catalyst.
A New Era for Superhero Films
With the introduction of the multiverse, Marvel now has endless possibilities to bring back legacy characters, reimagine storylines, and blend different cinematic universes. If Grammer’s Beast can make a comeback, who else might follow? Could we see Ian McKellen’s Magneto or Halle Berry’s Storm return?
FAQs
Will Kelsey Grammer Play Beast in Future MCU Films?
It’s possible! If “Avengers: Doomsday” is a success and the X-Men storyline takes off, Grammer could return in future projects, possibly in “Avengers: Secret Wars.”
Why Wasn’t Nicholas Hoult Cast Instead?
Since “Avengers: Doomsday” is delving into multiversal themes, it makes sense for Marvel to bring back different versions of iconic characters. Hoult’s Beast existed in the younger timeline of the Fox X-Men films, while Grammer’s version represents the older era.
Is “Avengers: Doomsday” Setting Up “Secret Wars”?
Absolutely! “Secret Wars” is expected to be the next major crossover event in the MCU, potentially uniting heroes from various timelines and realities. “Avengers: Doomsday” could be the stepping stone leading to that massive event.

Kelsey Grammer’s return as Beast in “Avengers: Doomsday” is a game-changer for the Marvel Cinematic Universe. It signals a nostalgic yet strategic move by Marvel to integrate the X-Men into the MCU.
