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.

Have you seen Cowspiracy? It takes a lot more land to feed a meat eater than to feed a vegan or a vegetarian. It's something I'd love to get into but it's very hard to persuade people to stop things they've been doing for a long time. So maybe it needs to start with the next generation. Everyone needs to raise their children with a bit more responsibility.

I knew I wanted to do something creative. I am dyslexic, so I really struggled in school. I knew I was never going to sit behind a desk or do something involving numbers.

Every year I look at the 'GQ' Best-Dressed List and have thought what an honour it must be to be included. I couldn't believe my eyes when I saw my own face in there.

I've had friends who have come away who've said, "I shouldn't have become such close friends with the director." You always want to get on with the director, but I personally prefer a relationship where you respect them - you get on really well with them, but they're boss, as it were. It's about trusting your director, for better or for worse. They're the one's seeing what's coming out on the monitors, so you have to try and trust what they say.

Often you find actors have big hearts; they're quite emotional people. Talking to actors who date other actors, and talking to people who deal with other actors, they often get emotionally caught up in lots of different things. They often wear their hearts on their sleeves. They feel things quite a lot - often to the nth degree, which I can imagine could make it quite difficult to date some of us. I think it's about having an emotional availability that you can kind of draw on. But I'm also searching for that. I'll be searching for the answer to that question for the rest of my life.

I grew up in London, and that's where I spend most of my time. Unless I have a really good reason not to be, I'll always be in London.
