You do remember things that people say in movies. You remember particular lines and things that are funny. But, you also remember really strong images. Images have a way of bypassing your brain and hitting you emotionally. There are so many things from movies that are remembered, that are just looks on people's faces or incredible vistas or beautiful pictures. That is a very important part of cinema.

I think you go through a period as a teenager of being quite cool and unaffected by things.

It is hard sometimes to see how other actors are working when you are working with them.

You are being hit with tabloid-journalism bi-lines of what you are doing because you have suddenly become a star.

It's a career that's enticing because you go on stage, for example, and people clap. You get that affirmation, but you can't go into acting for that because it's really your own self-belief that's going to get you through.

As an actor, I would call it a role where you get to stretch out a bit.

I think sometimes people haven't really quite worked out how to peg me, or exactly what it is that I do. In that way, I feel lucky that I can get to play different things because they haven't quite decided what I am.
