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 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.
