Hitchcock's got a very interesting voice; it's a very controlled, measured rhythm that's quite slow and, in that sense, also felt quite controlling in its pace. He retained something from his childhood, that London sound, as well as adopting some of the L.A. sounds... All of this helps you create the character.

Hitchcock is a big ask. I am playing someone significantly older than me and someone significantly bigger than me. The stuff I find very interesting is why certain physical things have come about. How can he be light on his feet when he is so big? How can his weight vary so much? Where does this rather beautiful voice come from?

I work best when a little scared, when there's so much more than the lines to think about.

It's hard to imagine anyone interested in film not being a fan of Alfred Hitchcock because he's such a key influence on the entire history of cinema - it's hard to escape his shadow.

We're interested by public personas and private personas, otherwise we wouldn't put on with actors rambling on with the same kind of stuff, over and over again, saying variations of the same thing. I'm always amazed by how fascinated people still are by actors because it's the same version of events that actors describe, all the time.

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