We [ with Russel Crowe] had an Arabic coach there [ in the Body of Lies] that was really helpful, because it was more so than any accent. You have to be so exact, and there's different dialects of Arabic from country to country so it was really, really difficult to tell you the truth. And one of the hardest things I've ever had to do language-wise, because it comes from the throat. It's different. And also learning about the customs and the culture and all that, so we had advisors for that sort of thing.

I'm probably not going to get married unless I live with somebody for 10 or 20 years. But these people, Romeo and Juliet, took a chance and they did it. We don't have the balls that Romeo did.
