We sing a lot of the soundtrack in this film [Swiss Army Man] - me and Paul Dano - and on the last day of filming we had to just get into the back of our sound mixer's van and record a really crappy, rough version of the singing then. For some reason that was one of the most fun days.

Potter for me is something that's been giving me these amazing opportunities to start a career and learn while I'm doing, which is the best way to learn.

You pick projects for the part, the director, and the script. I just want to do different, interesting stuff.

Somebody I love and have a huge amount of respect for once told me something that, to this day, I don't really think I understand. It was probably toward the end of Harry Potter, and they were talking to me about afterwards and that kind of stuff. And they were saying, "You need to think of yourself as a brand and you need to protect that brand." I just don't understand what that really means in terms of being an actor, and I also think I would find that a slightly soul-destroying way to look at myself.

I'll say American for now. I really have no preference, though. Nationality is nothing. It's all about the girl - but she has to be curvy!

Just keep acting is my plan, I just want to keep going for as long as I can. I've had a fantastic time on Potter, I will be very sad to leave it because every time I look back on one of these films, every scene I watch will be forever linked to a memory of what happened that day or something that was happening around that time in my life.

I'm not clumsy; just accident prone.
