When you're in the head of the character, you feel less self-conscious. If I was just being me, I would feel so exposed and be like, 'Why is there a huge camera in my face?' But, when you're believing in the person that you're playing, you feel protected. It's about being true to that person you're playing.
I was so passionate about wanting the role in 'Like Crazy,' I filmed myself in the shower because that's where one of the scenes was set. It just felt instinctive. It was a close up! It would have been strange if I'd sent off a wide shot of myself. That's not the kind of work I want to do!
I've heard directing talked about as being a benign dictatorship, and I think that's probably the best way a director should be. They're open to collaboration and feedback from people, but ultimately, it's got to be that one person's vision. That's what I think makes a film really stand out.
On 'Rogue One,' we had these sets with tiny little buttons that would light up when you pressed them, and screens full of graphics, and it really felt like you were driving a spaceship. The level of detail; you'll be two meters away from where the action is, but there'll be a little detail there just in case the camera catches it.
My grandmother has dementia, and my mother is looking after her as her primary caregiver. Seeing their relationship has had a profound impact, seeing how tough it is for both of them and seeing how the roles change and how my mother has gone from being a daughter to being the mother.
My agent called me up and said, 'There is a tremendous female lead in the new 'Star Wars' film, and I think you're really going to like it.' The opportunity to play someone determined, who's trying to find her skills as a leader; to be in a fantasy movie; to be able to do a leading female role in a film of that scale - that's very, very rare.
