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

As an actor, I think sort of relish the chance to take a leap and sort of put yourself out there. You know, it's, like on any film, you just have to be willing to embarrass yourself, because otherwise you are not going to really reveal anything that you have. So I think it's exciting.

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 would say I was challenging the system quite. But I like to think that if the choices I make are slightly unexpected or challenging to people, then that is good. We are definitely three fairly like-minded people in terms of what we value in scripts and in storytelling.

I get constantly mistaken for Elijah Wood.

I feel very English in a suit. There's something about being in a suit abroad, particularly in America, that feels empowering.

I think it's kind of great, to be honest. I'll never do another film [like Swiss Army Man] where I get to talk about those things, so I might as well enjoy it while I can.
