Back in September is was announced that Johnny Depp would be returning as Captain Jack Sparrow in Pirates of the Caribbean 4, however nothing else was revealed apart from that it may be released in 2012 and a script is being written. As 2012 is far off there have been no casting updates and there probably won’t be for a while, however Bill Nighy, who played Davy Jones in Pirates 2 & 3, has told MTV he would like to get his tentacles out once again.
“I am technically dead but then again, who cares?” Nighy said to MTV News. “Everybody dies in the pirates movies. They killed Johnny [Depp] and Geoffrey [Rush]. Death is not permanent in the pirate world. I have a serious desire to come back.”
At the end of At World’s End it hinted that Jack Sparrow would be going after the Fountain of Youth. Whether Davy Jones could fit into that is up for the writers to decide. They managed to pack a lot into the last film so it isn’t out of the question.
