McAvoy, who plays Professor X in the upcoming prequel, spoke to Screen Rant about his character, stating that he is rarely involved in the movie's fight scenes.
"[Professor X] is not too combat savvy in this film, it has to be said. He doesn't do too much, he's sort of a consultant with the combat guys," said McAvoy.
He continued: "But he does get involved in a few little bits of fisticuffs, I wouldn't say that he comes out well in any of them, but I wouldn't say that he gets his ass kicked either. Yeah, he's not particularly combat ready."
The actor also addressed the rumours about the ending of the film, which reportedly concludes with Professor X bald and in a wheelchair, as the character appears later in life.
"You'll have to wait and see, you'll have to wait and see," McAvoy said. "It's actually quite satisfying when you get to say that: 'I'm not allowed to say'. Because nobody’s actually told you that you're not allowed to say, but it's sort of implied."
X-Men: First Class opens in cinemas on June 3.
