They're such hierarchical things, film sets, they're sort of mini societies. Often they're incredibly political places.

I'm one of those people, when I see a film, I believe it to be true. You know, sort of the authenticity of the camera and seeing things on a screen.

Making a film or doing a play are completely different experiences and entirely fulfilling, but completely unique. I also think one complements the other. People often say that theater is about flexing your muscles, and is actually real acting, whereas I sort of disagree.

I've never been someone that was sort of blessed with an innate talent of just being able to do things. I had to work at it and learn from mistakes.

My favorite film is probably the finale - 'Deathly Hallows: Part 2'.

If I do a film and have to get naked, that tends to dictate how often I go to the gym. Acting in 'Richard II' on stage was a huge physical workout, so I ended up more toned than I normally am.
