People who have car collections - I never understood that. I always thought that was unnecessary. It's not beautiful, it's not creative. It's just showing how much money you've got.

Those things [t hydraulic penises and prosthetic butts and all that] can be what's genuinely shocking about the movie [Swiss Army Man] because people wouldn't expect to be moved by any of it.

Being in Harry Potter is like being in the Mafia. Once you are in, you are never really out.

I Google myself to see what come up when you Google Daniel Radcliffe because that's always amusing.

The one piece of advice I would give to any actor is, if you want to go out on the street without being recognised, without even being looked at, go out with a 6ft 8in beautiful transsexual. No one gives you a second glance. Especially when you're 5ft 5in.

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.

I like the idea of being a youngish parent. So I've got energy to play football even though they'll be better than me by the time they're four.
