Things go wrong for me, all the time, with technology. I'm not familiar enough with it, and I'm too old school a brain to be able to figure it out. I'm dumb. Anything that I have to attack with my thumbs, for any period of time, makes me feel stupid. So, I try to avoid it, as much as possible, to protect my thumbs.

Puberty was very vague. I literally locked myself in a room and played guitar.

I do believe that you have to bring some degree of truth from yourself to the role [Sweeney Todd: The Demon Barber of Fleet Street ]in and I'll admit it here, I have shaved a grown man before. I have done it. And it wasn't Tim [Burton].

It really depends on what the screenplay is asking of you, and what your responsibility is to that character. You have the author's intent to deal with, you have the filmmaker's vision, and then you have your own wants, desires and needs for the character. It's collaborative. But I knew, right off the bat, that there was no way to go into some sort of pink-haired, clown-nosed character with Ronald McDonald shoes.

I've never been particularly ambitious. I'm driven by the moment.

When you play a character that exists or existed, there's a stronger responsibility that you have. You owe that person and then you owe the family, you owe history, you owe the victims, the victims' families.

I don't like watching myself in the movies because I don't like being aware of the product. I like the process. I enjoy that.
