I don't really know what kind of actor I am.

The only constant I can find is hard work.

In 'There Will Be Blood,' my character was someone who was an actor himself almost. He had a rehearsed quality about him. He was a performance artist in a way.

The idea of writer's block or not having inspiration is totally terrifying to me.

It's a funny thing. You sort of never figure it out with acting. You're always learning.

I'd always been fascinated by people who allow themselves to be so rude and irritated and foul-mouthed and hostile, but usually you can sense there's something vulnerable beneath them - a shield they use to protect that vulnerable side. Finally, when they expose that soft spot, it's kind of touching.

Homeless people really upset me when I was little. A lot of kids have this reaction, but I would get really worried or sad or concerned or cry.

I like a restaurant called Bruci, and there's some really nice people who work there and good food. They change their menu a lot, so maybe that's what keeps me coming back. I never know what I'm going to get.

I love Led Zeppelin and Black Sabbath and Guns N' Roses and AC/DC.

You look at the part in '12 Years A Slave,' you finish that script - I mean, it's a powerful story. You go, 'Man, I have to play a bad character in this.' And then you go, 'Well, do I want to play a bad character and contribute to a good story?'

Sometimes I think your intellect can get in your way as an actor or an artist. When you come from a world of improv and comedy, you're able to let it flicker and fall out.

There's that thing that if you want to have any kind of lasting love, I think you have to love the whole person and not just the parts of them that you choose.

The better the acting is, the harder it is to see what the process is.

Films can be entertaining without shying away from exploring something. They can be magical and have fantasy, but also can have enough reality that you can be really emotionally invested.

When you repeat yourself so many times, even if you're speaking the truth, the repetition starts to feel false. Sometimes, you just feel like the words you're speaking, even if they once had meaning, have lost it. And that makes you feel kind of silly.

I always ask for more takes. I like doing takes, so I'll do as many as I can.

I grew up in Manhattan, and now I live in Brooklyn.

I think the idea is to try and understand everything about the characters and where the character is coming from, from their point of view, why they say what they do. And not, 'Oh, but I would never say that. Why does the character say that?' But then making it as personal as possible.

'Looper' was a wonderful script. Rian Johnson is the real deal and a really talented filmmaker.

I'm a private person, but I don't feel afraid to walk out of my door or anything. I get recognised occasionally, but not overwhelmingly so.

I don't normally like getting dressed up, but when I go to events, I like to look put together. I've got to say, getting in a nice suit feels good.
