If I was left to my own devices, you would see about ten T-shirts in rotation with maybe a few nice pairs of jeans - but I also like to look good. I like feeling really well put together, I just don't have the aptitude and the knowledge to do that.

I think I'm always very naïve. With 'Kill Your Darlings' and 'Horns', I'm like, "Why wouldn't everybody love this?" But I guess it's going to divide people in some ways. But if you're willing to go with it and suspend your disbelief, you're going to get something amazing and something unlike anything else.

Sometimes you can't help but pay attention to what is written about you. You are trying not to because it's generally not constructive, it can be very funny, in which case it's fine to pay attention to it if you're going to laugh about it. But if it's going to get you angry then it's a pretty pointless waste of energy, so I try and be selective about what I take an interest in about myself.

I was very sad to leave Harry Potter but equally there will be an element of excitement about the idea that a script might come in and I don't have to go: "I'm sorry, I'm kind of busy for the next four years." The idea of that is quite exciting.

Well, I think I’m a feminist, just by the virtue of the fact that I believe in equal rights for everyone.

I'm a serial monogamist. I'm not one of those people that can date loads of people at the same time, it's all too complicated.

What first attracted me to doing Swiss Army Man was just how mental it was - how insane and wonderful and original the script was.
