My brothers are both 6 ft. 5 in., and if you have younger brothers who are bigger than you then you have to learn the ancient martial art of sarcasm.

You learn as much from doing a bad film as a good one.

As my mum still candidly says, I was the runt of the litter.

I've run out of mates that haven't had a baby now. It does make me think of my parents having a family so young and the fact that I've been able to avoid it for so long. It does make me a feel a little bit selfish.

No one thinks they're irritating. Nobody thinks they're boring. So if you're playing a character like that you have to play them as how they think of themselves.

I built up a knowledge of 1960s and '70s British films because my dad used to work nights, and I'd sit up with my mum and watch films - 'How I Won the War' and the films of Richard Lester, Karel Reisz and John Schlesinger.

Someone told me about drama schools, and they seemed like mythological places - you can really go and be in drama classes all day? I inadvertently entered into this world where people wore bicycle clips and did song-and-dance routines in the corridors.
