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

I had to change the shape of my own voice. It was quite hard to pull off and so once I had it, I stayed in Hitchcock's voice all day on set.

You're playing a character in a drama who happens to be based on someone who existed. It's never going to 'be' that person, but it's based on someone well-known, and you want to create enough of that person for it not to be a distraction.

I didn't sound anything like Capote at the screen test. It was more like Bob Dylan. In his early years. With the flu.

I get plenty of time to re-engage with the world I'm trying to depict, so I'm not always living in these parallel worlds.

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.

There's not a huge pile of scripts at home. It's what happens to be on the table at that moment with your availability. And then you have no control over when these things come out.
