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 always think of comedy as being spontaneous, and yet everything about filmmaking is not spontaneous.

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.

Actors who perhaps are super-confident and have absolute belief in themselves I always admire, because I can't really be like that.

The depiction of the exterior as opposed [to] what you're feeling inside is always so different that it's impossible to know what is right.

People ask, "Do you enjoy acting?" But you only have those specific few hours to do a scene, and then you drive home and wait for six months to find out how it went. You can't go back and put in a new idea. Filming is about continuing to be alert and to think, and I find it quite exhausting. Certainly I would say that fear is a part of that.

If you've loved something and then in some ways you become a part of it, you just don't want to be the one that screws it up!
