You could be right, but they're apparently good friends anyhow. Depp at least has some of the same musical interests/directions himself. He moved to LA originally as a musician, in a punk band called the Kids. He has a band nowadays with someone even crazier than Manson: Gibby Haynes (from the Butthole Surfers), called Pee. Among others. When his original band fell apart, he fell into acting by accident.. at the suggestion of another possible ILE friend: Nicolas Cage. Cage thought Depp was a natural actor, and got him his first auditions.
