The movie is so fun. I've done period pieces before but nothing with this twist. And the movie is just full of such wonderful people, such young actors - people like Matt Smith that I've been friends with for a while.

I live alone so I always just eat out. When I'm in another relationship, then maybe we'll start cooking together.

I actually wanted to be a jazz musician first. My grandparents introduced me to Louis Armstrong. I loved Louis Armstrong so I took up the trumpet and just did that every day and practiced that.

When I do go to L.A., it is usually for a reason - to meet with a director or something - but I'm always so happy to go back to London.

The negative about acting is that you have to spend a great deal of time away from your friends and loved ones, but it's not like working a 9-5 job and only having two or three weeks off a year. I may not have seen my girlfriend for two or three months, but then we can spend two or three months together solidly.

I like to cook Vietnamese pho or vegetarian curries. I need to cook more but I need somebody to cook with.

Nothing's been changed overnight. It's like watching your cat grow: you see it every day, so you don't really see it change, you wake up one day and it's a bloody great thing. Your friends come round who you haven't seen for a couple months and they're like, "Oh my god, your cat's grown so much again." And I'm like, "Has it?" But when you're living it... I just find that my life has subtly changed bit by bit, so I don't ever really notice it too much.
