Kate Mara had a "horrible experience" working on 'Fantastic Four'.
The 37-year-old actress doesn't "regret" making the 2015 Marvel movie - in which she played Sue Storm/ Invisible Woman - because it's where she met her now-husband Jamie Bell, but she does wish she'd "responded differently" to certain situations on set.
Reflecting on the "horrible experience" making the film, which was directed by Josh Trank, she told Emmy Magazine: "I've never talked about it before. I married one of my co-stars, so I don't regret doing that movie at all. But do I wish I had responded differently to certain things? Yes, definitely."
While Kate didn't go into the specifics of what happened on the movie, she admitted she had another "horrendous experience" on a different set, with she believed was due to a "power dynamic thing" from her male directors.
She continued: "The fact of the matter is that my two horrendous experiences with directors were male directors.
"Have I not gotten along with a female director? Absolutely. And was it not the greatest work experience? Sure.
"But there was never a time that I felt, 'This is happening because I'm a woman.' Where with the male directors, it 100 percent was only happening with me; it was a power dynamic thing.
"And on both of my bad experiences, the movies were 95 percent men and I was the only woman in the movie."
Kate admitted in a separate interview that she regrets not having "followed [her] instincts".
She told Collider: "I should have followed my instincts more.
"Like when my gut was telling me, ‘You probably shouldn't let that slide, what that person just said,' or if you're feeling a certain way about what an energy is like and how that is affecting your performance.
"You have the right to speak up and say, ‘I'm actually not able to do what I am here to do because of X, Y and Z.'"
The 'A Teacher' star admitted she put up with some things that made her feel "uneasy" because she was in a "big superhero movie," so felt that "even if it's challenging, it's probably good for you to do it."
She added: "I don't regret doing it at all, but do regret not having stood up for myself."
