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.

Everything about filmmaking is incredibly weird, and there's nothing natural about watching yourself on the big screen or hearing your voice. It's that same thing that you feel when you watch yourself on a video camera and you hate the sound of your voice - it's that times 800.

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.

Tequila is my salmon.

I always try to describe making movies like summer camp, or some holiday where you spend all day, every day with a new group of people whom you kind of love and then never see again.

I do get stopped a bit now and then, but I can go to the supermarket and on the Tube without being noticed. It's usually me that gets starstruck, especially by TV stars.

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