She told ComicBook.com, “I remember Jennifer Lawrence talking about once, how long it took her to get blue [for X-Men]. And I was like, ‘That seems like hell on earth,’ because then you get to set, and you’re only there for a couple hours, and then you have to take everything off. And that was literally the reason.”
However, she later told the Hollywood Reporter’s Awards Chatter podcast, “I didn’t want to be part of the first Marvel movie that bombed. … The script was great, it was all based in not wanting to be ‘that guy.’ Because if you are the star of a giant movie like that, and it bombs, Hollywood does not forgive you. I’ve seen that happen to people and it was a giant, giant fear and I thought, is it worth it?”
The role went to Zoe Saldaña.
