All these things, social media or [smart] phones or the things that distract us from each other, are fairly new. They're all fairly new inventions, and I think we're in a stage where we sort of as a whole have gotten these new toys and we're just obsessed with playing with them. I feel like after a period of adjustment it will inevitably be a regression from where we are now.

I used to joke I was a point-and-click actor. My whole process has been about trusting your instincts and hitting your mark.

I think I tried to steal a Mars bar once from a shop but then I went and put it back.

I'm possibly a very morbid person but I think about death a lot. I don't know if it's maybe from being on films that's often playing Harry [Potter] or I just think it's a natural thing that I have. It's something that I think about just because it's fascinating in a very alien kind of way.

I sort of try to read the books when they come out impartially and not make up my mind, but the fact is when I was reading the sixth, 'Harry Potter And The Half-Blood Prince', there were bits in there where I was going, 'God, I would love to do that because it's so good'.

I would consider doing any part as long as the script is good and the film has an interesting director.

Don't try too hard to be something you're not.
