Some people can very easily switch off and be guilt free, not that what I'm doing is about guilt, but they can completely disconnect and not care because it doesn't affect them. I've always really cared about what happens and felt a certain responsibility.

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.

It's better to think of life as a proper journey with a beginning and an end. Maybe, I can settle for being immortalised on screen.

One of the biggest things I used to struggle with was about things like going on holiday. Whereas all your friends can talk about something and plan something all year long, I know that I'm probably going to be away and I'm going to miss all of it. If a job comes up, you just can't be there.

You're always going to have ups and downs - if you look at the careers of a whole bunch of people I respect, some of them have good movies, some of them have bad movies. I remember Andrew Garfield said that the only power we really have as actors - or one of the main powers we have as actors - is our choices. We can make interesting choices, but as soon as you've made that choice, so much else is in play: the director, the script can change, the other actors. All you can do is try to make interesting choices and, once you're in it, just do the best you can.

I like to travel, but honestly I really like to just be at home in London and spend time with my friends.

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