"The Fly was a major hit for me. In fact, it's still is my biggest hit relative in dollars. It was technically very challenging but it reminds me of some of the things I’m doing now like Cosmopolis because it's just three people in a room. People don’t think of it that way, but it is: very claustrophobic and very intense. I think of it as the beginning of my Samuel Beckett period: a kind of austerity, control, rigorousness. We were working in confined spaces, something that I rather like. People keep asking if Cosmopolis's limo scenes were confining, but I find that a confined space adds to the intensity of the drama and helps the actors too. It’s not a challenge; it's liberating and exhilarating."
