There's something that happens where you go, if you're lucky, goodness me, from film to another film to another film. And you can sort of feel that if you step off that treadmill, it might all go horribly wrong and you might never be employed again, you know. And I suddenly thought that that's not necessarily the case. And I also thought we make drama as actors about people in the world and that if you are on that treadmill, you start making films about other films.

If I'm playing music in front of people, I'll lose days to nerves like really wasted days of just like being terrified. And then when I get out there, generally speaking, I enjoy it very much. But it seems to be I have to accept the fact that that's just part of the deal for me. And I can't just run on and do it.

For the actors, there's something very important about that first showing of the scene to the crew, becomes like a little performance.

A million pounds sounds like a lot of money now that I'm saying it. But in terms of moviemaking, it's not a lot of money. And yet you can see what can be done with that, with the talent of a great cinematographer and great director and actors.

He`s quite extraordinary with his moves and spins. I think he was a baton girl in a past life [on his co-star Hayden Christensen].

It is always a nice feeling when you are challenged by a scene and you walk out of trailer and you go on set going I don't know. And then half an hour later you're walking back.

It's impossible to put your finger on what that is exactly other than protecting the environment that the actors get to find the scenes and build the scenes and invest in them. I think that's key and that's what I've learned from all the great directors I've worked with.
