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.

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'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.

'HIM' is much more of a British, coming-of-age series, while 'Stranger Things' is very obviously a sci-fi drama.

There's a restaurant I go to whenever I can called The Richmond Cafe. It's a little Thai restaurant owned by a group of Thai women - I think they're all a family, and they're just really, really nice, and they make amazing massaman curry.

My 'Dunkirk' co-star Harry Styles deals with some crazy fan stuff, but he's a very down-to-earth, lovely, funny guy.
