Most actors hate watching their own films because all you can see is the glaring mistakes, your own tricks and ticks.

Learning lines is hard for me because I have the attention span of a six year old. That's why being on planes all the time is so useful - I'm forced to learn out of boredom.

I love the Potter films. I found them the most wonderful sort of escapism every year or two.

It can be a miserable profession, acting, because you always want what you can’t have.

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.

My first film, 'Like Minds,' was with Toni Colette, who was extraordinary. I mean it was basically a mini-masterclass for acting on film at a time when all you could probably see were my eyebrows bouncing up and down on screen.

The fear of messing up is what makes you work harder!
