Going over to Lesvos in Greece and meeting some of these poor refugees who have just made the treacherous sea crossing opened my eyes in a way I can't even being to describe. It's put a fire in my belly to really try to do something, the little I can do.

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.

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.

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 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 like to wake up late, around 11 A.M., especially if I have been out the night before. Then I go to brunch with either my friends or my girlfriend. I then like to just chill out: read the papers, read some scripts and then take it very easy. If it's sunny, I go for a walk with my dog, Niles, in the countryside.

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