I have never been insecure, ever, about how I look, about what I want to do with myself. My mum told me to only ever do things for myself, not for others.

I just think they're really insecure about themselves sometimes. I know all the girls, but we all work a lot and don't have time to hang out together. They're all really nice; I've never had a problem with any model.

The worst thing to do when I'm feeling insecure or a bit vulnerable is to scroll through Instagram. You only show when life is good on social media. Everyone looks happy all the time.

I think directing in a team is a really good idea because it stops the cult of the director as God straight away, and also you're discussing things on set so it opens it out to everyone and it becomes a totally collaborative thing. And you have someone who supports you when you're feeling a bit insecure.

I love playing strong feisty women, I really do, but if you were to ask my husband he'd probably say that I'm very insecure. And actually incredibly malleable, which isn't necessarily a good thing.

I've really fought to get into rooms, and I'm a big believer in auditioning. It's hard, because I'm insecure, but I have an intense desire to prove myself to people.

Actors are dumb when they get insecure of their co-stars. A lot of actors do. When there is a good actor, they're like, 'Oh, he's eating up the part.' That's stupid.
