I feel arrogant trying to give people advice.

When I find a look that I like, that's my entire wardrobe.

I hate the word "method acting." It's just so silly. You hear people going, "Yeah I'm a method actor." I'm like, "So what happens if you're playing a period film or something? You're in the Second World War. And what happens when your mom calls you on your phone? Do you go, 'Oh! What is this strange talking brick device?'" No. It's stupid. But you do everything you can to get in that mindset.

Each year we go to the Cannes film festival and I tend to have all my friends pile in the back of my car and we'll drive from London. The poor production company think they're only putting me up and suddenly they've got eight people sleeping on my hotel room floor.

When I was growing up, there was a man who gave me lessons and things. I'm very dyslexic so he used to give me extra reading and writing. And he always knew that I was interested in stuff but he never told me that he was in the Second World War himself. One day he gave me his helmet that he had worn through the North Africa Campaign. It was just before he died. So I've got his helmet. That was pretty special to me.

On the whole, British actors star in theater, and I think there's something quite grounding about that.

I actually collect old First and Second World War memorabilia.
