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.

If you go into acting to make money then you're an idiot. It's my hobby and the fact that I'm doing my hobby for a job is mental.

'Great Expectations' is one of the greatest stories.

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.

I collect old first and second World War artifacts and things. I'm a little secret history nerd. I've been lucky enough to do quite a few war movies too so I've taken little things off each film.

People expect your life to change completely. The main difference is I can get work now. I can do my hobby as a job. It's great. It's a privilege. But in terms of the rest of the stuff, I still got all the same group of friends I always had. I don't do anything different. We still go to the same dirty bars and do the same things. So nothing really changes.

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