Being self-critical is good; being self-hating is destructive. There's a very fine line there somewhere, and I walk it carefully.

I could never do stand-up because it's that thing of having to get up on stage. And out of every 10 jokes you tell, nine of them have to get a really good response.

In some ways, you get to find your voice better in [a sequel] because you have to define how you're doing it differently.

I played bass for a year, but I wasn't getting better at it, so I decided to stop so I could see my friends.

I certainly want to establish myself as an actor in my own right, rather than being just the actor who plays Harry Potter.

And the people I'm best friends with on the films are not generally the actors.

A lot of modern horror can leave me cold, and I'm not good with blood and gore and all that stuff. It's not fun for me. There's nothing entertaining about watching a film like that.
