Johnny Depp has said that he was excited about being able to work with Rolling Stones member Keith Richards again on Pirates of the Caribbean: On Stranger Tides (2011).

Richards returned to the film franchise to reprise his role as Captain Jack Sparrow's father Captain Teague, and Depp revealed that he enjoyed spending time with the rock star.

"To be able to bring him back into the Pirates fold, where he most certainly belongs, was a gas," Depp told the Associated Press. "Just spending a couple days sharing a trailer, it was as close, I suppose, as being in a rock 'n' roll band with him as you can get."

As well as praising Richards, Depp also responded to early rumours about a potential fifth instalment in the popular Disney franchise.

When asked what would be needed for him to star as Captain Jack for a fifth time, Depp said: "Essentially the same ingredients that have gone into each and every one, especially this one."

He added: "I would be in if it was right, for sure."

Depp recently claimed that plans for a fifth film were still uncertain, and that his involvement would depend entirely on the quality of the script and director.

Pirates of the Caribbean: On Stranger Tides is due to open in the US on May 20 and in the UK on May 18.
