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

I really don't want to go to work every day convincing myself of what I'm saying. I want the material to make me a better actor; then I try to return the favor to the material.

I think 'American Pie' is great.

I volunteered at a homeless shelter in preparation for 'Being Flynn,' and when I'm walking along the Bowery, that's the first thing that comes to mind. That's a nice memory.

Have I seen any plays that I've been in? Uh, you know, might be a little weird.

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

When I'm not excited, it makes acting very hard for me.

I used to write a lot of songs. I was an English major in college. I was a deluded poet for a year. Totally deluded.

When I'm not acting, I like to go home and be really normal. So I usually grow out my hair until I get the next part.

It's a lot of fun to be a part of films that you don't exactly know how they're going to turn out.

I like listening to my playlist on the iPod. I don't want radio with commercials.

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?'

I think it is important to make sure that I have my real life as well, because Hollywood can certainly seem like an alternate reality sometimes.

Some projects go as you hope or imagine, and some change or reveal themselves in a different way; it depends.

I approach every role from scratch.

I feel like, once you're doing a job, you shouldn't talk about it.

I've definitely been in ruts, and I think having some kind of perseverance is important.

You try to get to know your character as best as you can before you start filming - what's written and not written.

I sort of grew up doing theater. And that's how I got into film, actually.

The way Hollywood works, you're never sure if their first thought is to make a great film and honor the material or just another business property.

I can obviously relate to a character who is an artist, because the creative process is a big part of my life.

I think was overly empathetic for a while in my life.

The whole being-in-a-room interview thing, at a junket or a film festival, is very inhuman. You meet the person, have five or 10 minutes to talk, and it's not like a conversation.

I remember going to the theatre when I was little and the lights going down and just getting really scared about what was going to happen up there.

Everything you do, every experience that you have, enlightens you a little bit or worsens you.

One of my favorite films is 'Dumb and Dumber.' I'd love to do some really silly comedy someday.

Being actors is a strange job.

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

As an actor, the toughest thing is being subject to circumstance. Meaning: What scripts are out there that are available?

People have asked me about playing outsiders. I don't consider myself an outsider. Maybe that's why I'm interested in that. I'm not really sure.

I don't want my learning curve to be stunted by just all of a sudden doing work all the time and not being careful about the work that I'm doing.

I've seen people, where if they have to wait around the set for three hours, and they call you at the wrong time, and they're not ready for you, some people don't like that.

I love filming in New York. I love New York movies, too. I just like it when people can take New York and make it their own, because there are so many different New Yorks.

Theater is hard.

Certainly, being on stage is a rush.

I don't know that praise is always a good thing.

Nobody is a perfect actor.

Creativity, for a lot of young people, is a coping mechanism. It's the only place they feel comfortable. It's the only time they feel like they're being heard or can make a difference, is if they can go into a room and do a drawing or go to a garage and play a song or retreat to this world.

There was a time I was willing to be a clown for people who I felt were the perfect person for me.

We had established Harley Quinn as an accomplice to the Joker who was also crushing on him and found herself in the middle of this weird relationship being at the beck and call of his every whim. We wanted to stretch her and make her a stronger character, so to have her leave him and go off on her own was a story I wanted to tell for a while.

'Boo & Hiss' has been a passion project of mine for a couple of years. I was intrigued with the idea of what would happen in a classic cartoon predator/prey relationship if the predator - in this case, a cat - got to finally do in his adversary only to have the mouse return as a ghost and bedevil the cat.

If we made the 'Batman' games more realistic, you'd have to be Bruce Wayne for half the game, counting his money and dating supermodels.

I was writing a script about the Joker menacing a regular person who had strayed into his path, and I needed to give him a gang of henchmen to work with him. The idea occurred to me, let's put in a female henchperson, because that seemed like a fun variation on the regular big thug guys.

One Thanksgiving weekend, I had a lost weekend at a friend's place with 'Grand Theft Auto.'

Batman doesn't use a gun. When Bruce Wayne thinks he had to resort to a street thug's level to defend himself and the girl he was rescuing, he decides he can't be Batman anymore.

I've always liked the Krampus character, and I've always been fascinated with him, especially the tradition that he was such a part of the holiday season in Europe, in Germany, Austria, northern Italy, various other places.

I was one of those goofy kids whose year narrowed down to focus on Christmas from about September on. I guess I was like Ralphie in 'A Christmas Story,' in that I would get swept up into the anticipation of the holiday, watching the lights go up, hearing the songs in the stores, getting special Christmas issues of comics and all that.

Mr. Freeze is motivated by different things. He doesn't really have that much of an axe to grind with Batman. Batman is an irritation and an impediment to him, not an enemy that he hates. He doesn't have the hatred that the Joker has for Batman.

I take inspirations from newspaper strip cartoonists who look for ways of expanding their characters' worlds once they have established the initial concept of their strips.

Without Wonder Woman, there would be no Black Canary; without a Superman, there would be no Flash. They all come from that.
