The X-Men MCU reboot has reportedly found its Beast with one of the stars of A Knight of the Seven Kingdoms.
While the majority of the cast for the highly anticipated MCU reboot of X-Men was announced at D23, there are still major roles that are yet to be cast, including Beast. Fans have been wondering which actor Marvel Studios will cast to play the beloved character and whether it will be a well-known star.
Now, it looks like we have finally found our new Beast.
Who Is Reportedly Playing Beast in the X-Men MCU Reboot?
A report from Knight Edge Media claimed that A Knight of the Seven Kingdoms star Peter Claffey has been cast to play Beast in the MCU reboot of X-Men.
In case you're not familiar, the actor plays Ser Duncan "Dunk" the Tall in the HBO prequel series, which aired its first season earlier this year and recently wrapped filming its second season.
So far, Marvel Studios has not confirmed the report, so we still have to take this news with a grain of salt. However, the outlet has reported accurate scoops in the past.
The character was previously played by Kelsey Grammer, who is reprising the role in Avengers: Doomsday, in the original Fox movies, and Nicholas Hoult played him in the First Class era of the franchise.
For now, let's wait for official confirmation from Marvel on the casting, but fans online have expressed excitement about the possibility of him playing the role, especially since he has the physical look that fits the character.
