I still don't feel I know Hitchcock at all. I find that the more one looks, the more elusive he becomes. But my admiration for Hitchcock the filmmaker remains undiminished. He is a giant of the cinema and the darkness in him informs his cinematic language. You can't separate one from the other.

I teach for the Book Trust, which promotes reading and writing with children.

I'm very interested in people, so if a character happens to be real, there's that much more to look at.

Jennifer [Lawrence] is amazingly grounded in the midst of all this to do. It must be unnerving and hard to relate to the amount of attention she generates.

The thing about Hitchcock which is quite extraordinary for a director of that time, he had a very strong sense of his own image and publicizing himself. Just a very strong sense of himself as the character of Hitchcock.

You can't deny reality just because you can't explain it.

I would absolutely like to play more leading roles. There’s no philosophy - well, the only philosophy, I suppose, is to try and do different things.
