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 had friends who ran off to become ski instructors or worked in cool bars, and I often envied them, but I know I'd quickly become bored with that kind of life. I always need to push myself.

Obviously, you never shoot the scenes of a film in order or only very rarely.

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.

With our job, you often meet people through work. I've had two long-term relationships, from 14 to 18 and 19 to 21. One I met at school and the other I met on a job so who knows where I'll meet the next person.

Sometimes things are nothing on paper, but a genius director turns it into something amazing.

I dreamt of being an actor ever since I was young.
