Sometimes, a job just doesn't stack up the way you thought it would when you agreed to do it. Rooney Mara's problem wasn't anything to do with the quality of the script for 'Pan,' in which she played Tiger Lily. She didn't think it was a bad movie, and she didn't have any issue with anything that she was required to do on the set. It was the way that people reacted to the film.
What Mara hadn't thought about when she took the part was that, strictly speaking, she was the wrong race to play the character. The movie was accused of 'whitewashing' the story, and led to a broader conversation about diversity and inclusivity in Hollywood, with her part frequently being highlighted as an example of people from ethnic minorities being denied roles. She says she's learned from the experience, and will never put herself in that position again.
