I like physics. I think it is the best science out of all three of them, because generally it's more useful. You learn about speed and velocity and time, and that's all clever stuff.

I had a great childhood.

If someone tried to take the hierarchy thing too seriously - for example, being lovely to producers but moaning to runners about the tea - that would not be accepted on 'Harry Potter'; someone would pull you aside and have a word.

I like geography. I like to know where places are.

I'm not one generally to do that stuff anyway, and they didn't even ask me whether I'd seen the show [The Flash]. They didn't tell me anything about what I was going to play, they just inferred that there was going to be a lot of meat to sink my teeth into.

I started my own record label.

I live right in the middle of nowhere and I thoroughly enjoy it.
