Hollywood star Johnny Depp was shocked by Rolling Stones guitarist Keith Richards' acting skills - because they were so accomplished. Richards appears in the forthcoming Pirates Of The Caribbean movie, At World's End, and Depp has praised his co-star's aptitude on his big-screen debut. He says, "Keith did his bit like it was any other gig - he did it perfectly. "It wasn't like, you know, people could tell that it was his first cinematic venture. He was just perfect."
