The spirit of Dunkirk is something everyone grew up learning about. After Dunkirk, everyone came together and it set the tone in the U.K.

I'm not really a green juice kind of guy. I like feeling downtrodden and worthless when I walk around London and have someone click their tongue at me and tell me to speed up.

I think you can overthink dealing with fame. To an extent, you've got to put yourself out there, but I feel like your work should really speak for itself, and I don't feel the need to go and make everyone like me because, to be honest, I'm not looking to be friends with the world. I'd much rather people watch the things that I'm in.

I don't really think much about how I would have fared in the Second World War. It's a topic that has to be treated with respect and subtlety, and you can't just go in all guns blazing and make an epic action film.

You make yourself do the physical aspects for a Christopher Nolan film!

I like to think I'm fairly grounded, and I have friends who will very happily tell me if I'm ever being big-headed. I know things will change. But I'm hoping it's nothing too drastic.
