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.

I would be the last person on earth to complain about what I do - I feel very fortunate and I know there are a million jobs in the world that are much, much harder - but it's not always an easy or glamorous thing to do, that's for sure.

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.

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.

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.

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.

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.
