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'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 like the dueling club scene, where Daniel and I fight with our wands. I thought it was a brilliant scene to shoot. I think the end product looked really good.

A nice pop star would do you nice on one of those deserted islands.

When we're not trying to kill each other with spells, we just sit in in Daniel's dressing room watching cricket games on television.

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

I'm a real big country boy.
