Johnny Depp

The 'Pirates of the Caribbean' actor has said a number of times that he likes to keep a sense of "ignorance" when it comes to his work on the big screen.

Depp told talk show host David Letterman in 2009: "In a way, you know, once my job is done on the film. It's really none of my business. I stay far away. If I can, I'd try to stay in as profound a state of ignorance as possible."
