Halle Berry opened up on the difficulties she experienced while shooting the X-Men films with Bryan Singer.

"Bryan’s not the easiest dude to work with," she told Variety. "I mean, everybody’s heard the stories — I don’t have to repeat them — and heard of his challenges, and what he struggles with."

"I would sometimes be very angry with him," she added. "I got into a few fights with him, said a few cuss words out of sheer frustration. When I work, I’m serious about that. And when that gets compromised, I get a little nutty. But at the same time, I have a lot of compassion for people who are struggling with whatever they’re struggling with, and Bryan struggles."

Berry mentioned that Singer "didn’t always feel present" during the filming of X-Men: Days of Future Past. She recalled times where the cast and crew would be freezing on set while "he’s not focusing," leading to some resentment from them.

Despite showing sympathy for Singer's circumstances, the X-Men star believed in changing Hollywood's work culture. "Clearly, things need to change," she said. "And what we as women were acquiescing to, and were allowing needs to change. And it needed to get blown up. And people needed to be outed."

Berry's account comes months after X-Men producer Lauren Shuler Donner revealed Singer's behavior led her to sit out the film's premiere.
