Tom Cruise, Def Leppard, Bret Michaels and More Celebrate 'Rock of Ages' Premiere

Were there any artists you looked at for inspiration?
I hadn't studied music in the way that I needed to play a musician, so I went back and studied it. Adam [Shankman] gave me a lot of books, and I also called Cameron Crowe and he gave me some biographies to look at, [including] one on Led Zeppelin. I looked at the Eighties, I looked at these guys, [but] I had to make the character my own. You look at the styles, [and] when you start working on something, you just kind of become something else. 

How nice is it be able to go to Cameron for advice on playing a musician?
He wasn't directing this film, but he and I were exchanging emails and I said, "Take a look at this stuff." And he was very encouraging.
