Nicholas Hoult will be returning as Beast, repeating his role in X-Men: Dark Phoenix. Hoult revealed that the movie has production is still ongoing, and that he’s looking forward to something “very different” for Beast this time around:
It’s very different for Beast this time, and that was part of the appeal of doing the movie for me. Simon Kinberg who wrote and directed this time had great ideas for where he wanted the character to go, so I was excited.
