Our source says that Pirates of the Caribbean 4 is no longer just a possibility, it’s almost a certainty. More importantly, Johnny Depp is all but assured to return, though our scooper claims he may end up making as much as $35 - $40 million to do it. Also returning will be Geoffrey Rush and Gore Verbinski as director, but forget about the rest of the cast because from now on the movies will only be about Captain Jack.
