Johnny Depp has praised Keith Richards' work on forthcoming Pirates of the Caribbean movie At World's End.

Depp, who plays Captain Jack Sparrow in the Pirates films, was thrilled with how naturally the Rolling Stones star fitted into his first ever big-screen role.

"Keith did his bit like it was any other gig - he did it perfectly," Depp explained.

"It wasn't like, you know, people could tell that it was his first cinematic venture. He was just perfect."
