Johnny Depp has said that he would be game to do another Pirates of the Caribbean and why not. The movies are well crafted juggernauts that are money in the bank for everyone involved. Oddly enough when asked for a comment Orlando Bloom said he had not been asked to be involved in a 4th installment. It could be that its just too early to think about another film or maybe we could be looking at a prequel. The early adventure of Jack Sparrow?? Time will tell.
