Robert de Niro has always been fascinating to me. And if John Cazale were still alive, that would be a man I'd love to work with. I'm a big fan of Paul Thomas Anderson's films - I would be honored to work with him. I think he's a brilliant director, and he gets such compelling stories out of his actors and out of his crew.
I think we can all learn things if we really want to. It's fascinating how that can get expedited when you have a support system around you.
I did this film with Russell Crowe called 'The Water Diviner,' which took place just after WWI. It was fascinating because the weapons between WWI and WII were very different. I had to learn how to ride horses in a battle setting. It was important that we rode a certain way.
