There's plenty of girlfriend roles out there. They've come my way, and many people have turned them down, and I think, "Oh maybe I could do something with this." It's interesting when you get those roles, which seem like nothing on the page, and you kind of subvert them. It's hard to say no.

It seems like people increasingly just can't be by themselves because they're so used to having an epicenter on the Internet that actually exists for other people. Until someone clicks onto your Facebook page, it doesn't mean anything.

Some ideas, like what you're going to do with your life, take time to form.

o matter how much research you do, or invention you do, whether it's a character from a novel, a completely invented character or someone who actually existed, it's a work of faction. By the very fact you only have an hour and a half or two hours to tell a story, you're telescoping events and it is, in the end, a work of imagination.

The more you do it, the more you learn to concentrate, as a child does, incredibly intensively and then you sort of have to relax. I remember the first film I did, the lead actor would in between scenes be reading a newspaper or sleeping and I'd think, 'How can you do that?'

I had never done anything with blue screen before, or prosthetics, or anything like that. Lord of the Rings was like stepping into a videogame for me. It was another world completely. But, to be honest, I basically did it so that I could have the ears. I thought they would really work with my bare head.Working with Martin Scorsese was an absolute minute-by-minute education without him ever being grandiose about it.

Oftentimes you walk on set and then suddenly you're in bed with someone who you've never met before.
