Her quote: "We’ve talked about aligning our forces in the future. And here’s the thing with me… If you’re going to be in a superhero movie, you only get one chance. You’re that character forever. So why do a superhero movie and play the boring civilian? Whatever it is, I want a fight scene. I could be an incredible villain. I could be a hero. I want a cool outfit, and I want to kick ass. There was a thing…I don’t want to say too much – but there was one thing, there was a possibility in the future of the character becoming… And I was like, ‘I understand that, but I want to do it now."
Also, she already shot down "Captain Marvel" talk via a tweet:
I'm glad she didn't do the Iron Man 3 role, because it was SO disappointing. Rebecca Hall was wasted in that movie and Chastain would have been as well.
