I want to be challenged, I want to keep challenging myself - whether or not it's changing yourself physically or just pushing yourself to a certain extreme. I get bored quite easily so I like to keep my mind entertained by challenging myself.

I looked pretty crazy but at the time, you don't think anything of it. You think, "I've got an amazing job. I'm working and this is cool." I remember I was being fit to go to a premiere for something at Burberry and Christopher Bailey, who designs the clothes there, saw a picture of me and I looked weird. I had short black hair, hardly any eyebrows, I looked very very thin and he went, "We need to put Douglas in a campaign." So four days later, I was shooting a Burberry campaign because he had seen me looking crazy from the show so that was kind of funny.

I'd imagine a great date would be to go skiing. Imagine going skiing. Go ski with someone, if they can ski.

I got to be about 13 and everyone started playing guitars and being in rock bands. There was no place for me with my trumpet and I wasn't cool anymore. Although now if I played the trumpet it would be the coolest thing in the world.

I'm just trying to choose interesting, quirky projects or things with interesting directors or just movies that have a lot of people I like attached to them so I know I'm going to have a good time.

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.

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.
