They know you're not Alfred Hitchcock, but you need to be enough Alfred Hitchcock for them not to be bothered by it. That's a reassuring thing.

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.

Jennifer [Lawrence] and Josh [Hutcherson] seem very, very grounded. They're getting down to the film like they did last time.

What happens is some of the characters I've played have voices that are so different from my own, that it would be ridiculous if I would dip in and out of that voice in between takes to ask for a coffee, or something. Or to gossip about whatever was going on.

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.

I often get sent scripts about little men in big situations. There's a comic element to it, which is forces stacked against this little guy, and how is he going to defeat them?

Often jobs are un-turndownable even before you read the script. You go, "Well, I have to do that."
