I mean I've seen 3D films so far and I think it's a long way to go before they replace actors. It's a funny thing with 3D, I haven't quite got it yet. Yet.

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.

Mostly, I'm drawn to great characters and great worlds that use weird things for their language - whether it's dance, whether it's pop music with Justin Bieber, or whether it's magic.

I was very sad to leave Harry Potter but equally there will be an element of excitement about the idea that a script might come in and I don't have to go: "I'm sorry, I'm kind of busy for the next four years." The idea of that is quite exciting.

A gay murder movie is never going to be, like, breaking box office records.

The most wonderful thing I hear is people coming up and saying 'Thank you for my childhood', which still blows my mind but is very sweet.

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.
