One of the things that I discovered in my research is that some serial killers build an ultimate reality around themselves that they believe in, 100%.

If you're playing Hitler, you don't play Hitler as an asshole. Hitler believed what he was doing was right. Any of those monsters and any serial killer believes in what they're doing. I play it subjectively.

Acting gives me a chance to be people I will never be, in real life. I like changing who I am.

One of the things I like about doing historical films is drawing the line between now and then.

I think I come from a theatrical tradition where, if you look at the great theatrical actors of the British theatre, they took enormous pride in being wildly different from one role to the next. That's the tradition I come from.

What I went into the acting business for was to have a certain amount of chaos in my life. I don't know what I'm doing next. It's exciting. That's the way I like it.

I really do want to just be able to sit in the corner of the pub with my friends... to just be an actor and still go to the supermarket and not get bothered.
