I understood, through rehab, things about creating characters. I understood that creating whole people means knowing where we come from, how we can make a mistake and how we overcome things to make ourselves stronger.

If you don't know where you make your mistakes, that's your worst mistake: not knowing where your mistakes are at.

I guess the worst day I have had was when I had to stand up in rehab in front of my wife and daughter and say 'Hi, my name is Sam and I am an addict.'

The world is the great gymnasium where we come to make ourselves strong.

I tend to play characters that I can infuse with certain kinds of humour. Even the baddest guy can be funny in his own particular way. I want the audience to engage with the character on some deeper level so that they leave the cinema still thinking about him.

People know about the Klan and the overt racism, but the killing of one's soul little by little, day after day, is a lot worse than someone coming in your house and lynching you.
