I've always liked Terry Gilliam's take on Darth Vader: "I remember, years ago, talking to George Lucas about evil. He thought Darth Vader was evil. And I said, 'No, he's not evil. He's just the bad guy. You can see him coming a mile awayÑhe wears black. Evil is Mike Palin in Brazil, your best friend, the father of three, a good man, who just does what he does.'"
