Bryan Singer directed Romijn in “X-Men,” “X2” and “X-Men: Days of Future Past,” while Brett Ratner took over filmmaking duties on “X-Men: The Last Stand.” Several men have accused Singer of sexual assault, while various “X-Men” actors have called Singer unprofessional on set. High-profile actors such as Olivia Munn, Elliot Page and Natasha Henstridge have alleged Ratner sexually harassed them and acted rudely toward them on set.

While working with Ratner was a bad experience — Romijn said he was the only person she felt comfortable publicly throwing “under the bus” — the actor had a far better experience with Bryan Singer.

“He’s a fantastic filmmaker, you know? It was amazing watching him work,” Romijn said. “And you have to decide if you want to try and separate those two things. I know that the other cast confronted him about things. But I was not a part of that. I wasn’t there for it, so I can’t really speak to it.”

“There was drama on set, and I witnessed it and I heard a lot about it,” she continued. “And he sometimes didn’t come in prepared. But he would show up and, without any preparation whatsoever, direct the most awesome scene that he was able to put together because he’s such a good filmmaker.”

Several “X-Men” actors, from Jennifer Lawrence to Halle Berry, have spoken out publicly about Singer’s inappropriate set behavior over the years.

Berry, who played Storm in Singer’s “X-Men” franchise, said in 2020 that “Bryan’s not the easiest dude to work with.” Berry famously cursed out Singer on set one day and told him to “kiss my Black ass.”

Brian Cox, who played the villainous Colonel William Stryker in 2003’s “X2: X-Men United,” defended Singer’s set behavior in interview with Yahoo earlier this year. Cox said that Singer was “under a lot of strain” during the production of “X2.” Singer’s haphazard behavior often led to scenes being rewritten on the spot.

“I think he’s an extraordinary director — really, really gifted” Cox said of Singer. “Certainly I will always be grateful to him because he had confidence in me and got me the role. I played a waiting game and it worked.”

“There’s a lot of things at stake there,” Jackman said. “‘X-Men’ was the turning point, I believe, in terms of comic-book movies and I think there’s a lot to be proud of. And there’s certainly questions to be asked and I think they should be asked. But I guess I don’t know how to elegantly answer that. I think it’s complex and ultimately I look back with pride at what we’ve achieved and what momentum that started.”
