When I was 15 or 16 - I slept really well then. Now I sleep on a bed of anxiety-tipped nails.

Every time I do a movie, especially an animated movie, I just seem to scream and shout and hyperventilate for money.

I don't know why I get cast in a lot of period pieces. Stephen Fry told me that I had a face for period, that I look like someone from 1920.

I actually went to drama school at the Royal Scottish Academy of Music & Drama in Glasgow, so I stayed in my home town the whole time. However, I see more of my friends now than I did then. It's strange.

I did 'Narnia' because it was a good opportunity and all that, but really? I wanted to play Mr. Tumnus because he's my favourite children's character. That was awesome.

The script is the most important thing for me. I'm advised that other things are important too, and they are. The director that you'll be working with is hugely important, and the cast that are with you is really important as well. But, for me, the thing that gets my heart excited and really makes me invested in something or not is just the quality of the script.

I don't want to be all worthy about it, but I don't do red carpets, I don't do events and I don't accept freebies that much.
