When X-Men: Days of Future Past hit theaters last month, one of the many surprise appearances was that of Kelsey Grammer, who returned as the present-day version of Hank McCoy, a.k.a. Beast. While doing press for his upcoming action-thriller Transformers: Age of Extinction, the actor revealed that he hopes it wasn't his last time playing Beast, revealing he wants to return for another X-Men movie.
"I hope to do another. I hope they find some way to come up with a new story that involves Beast in my timeline."
The actor starred as Beast in the 2006 sequel X-Men: The Last Stand, but 2011's X-Men: First Class and X-Men: Days of Future Past focused more on these mutants' younger counterparts, with Nicholas Hoult playing the younger version of Beast. Kelsey Grammer revealed that he personally called director Bryan Singer and asked to be involved, following an encounter with Hugh Jackman.
"Actually I called Bryan. I bumped into Hugh Jackman and he said, 'Oh you're gonna be in another X-Men, mate!' and I said, 'No I'm not, I don't know anything about it.' So I made a couple of inquiries, got a hold of the script, found out that it's primarily dealing with the past and that timeline I don't have a place in, but I saw that at the end there was this coda where he made an appearance. I said, 'Listen, I really wanna be involved,' so Bryan arranged for it and I had a lovely time."
The next movie in the franchise, X-Men: Apocalypse, is set in the 1980s, so it isn't known if there will be a way to bring the present-day Beast back for that movie. However, given how X-Men: Days of Future Past ends, setting up a brand new timeline, it's possible that new world will be explored in some way.
