It takes such a particular amazing and extraordinary type of personality to become an actor. I love them. You can't do my job without them. I've worked with a lot of film actors and most of them are so, so prepared in their approach because they are used to turning up ready to shoot: you have to have your performance, you have to have your lines, you have to have everything pretty much decided and ready to go whenever everyone else is ready.

People grow and change and develop through their experiences, so ultimately you have to go with what's in the room - the feeling you get from them and what the camera picks up.

The camera kind of finds things that the naked eye can't even see. By moving in a certain way, you're already telling part of the story.

I've got Tom Hiddleston playing Henry V. I don't want to have a bowl haircut. I want him looking good so, you know, I want him in delicious kind of tight fitting leather jackets. [] I don't want him in tights, so he got nice leather trousers in mine.

When you're casting, you have to do quite a bit of research. But I always think you have to do it with a pinch of salt with actors, because it's so unfair to pigeonhole them and so often they are. I try to be as open as possible and if people are really interested and really want to have a go, then let's get them in and see them.

I ran the Gate in Notting Hill for a while, which is where Stephen Daldry started out. Those theaters are magical, because there's no money, so in a way there're no boundaries and it allows you to be inventive and brave and take risks and all those important things while you're starting out.
