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

I don't know if it's harder but when you're playing a real person you want to honor their memory - even if they're a criminal or someone that the public loathed. That can be challenging.

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

One key element to Hitchcock is the drooping jowl. That was crucial because his silhouette is crucial. There is something about his silhouette that became his brand.

Best ever was filming in Barcelona last year, and I had a couple of scenes with De Niro. He's a very shy man. Speaks so quietly that people tend to bend down and adopt the same tone, almost the same voice, whenever they talk to him - watching, you'd think someone's offering to carry out a hit for him when they're just offering him a cup of coffee.

We're blessed with, as we were on 'Harry Potter,' lead actors who are amazingly grounded people.

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.
