Those "Pirates of the Caribbean 4" rumours just ramped up a bit with a report from Cinema Blend suggesting that sequel number three isn't just a possibility, it's a certainity.
Johnny Depp and Geoffrey Rush will return for the next film - nobody else from the original three films will return as the series will now center on Jack Sparrow, played by Depp, says the site - with Gore Verbinski slated to again direct.
The site's scooper says that the next film could be an out-and-out-science fiction film. "Some of the brainstorming going around involves some Jules Verne type of scenarios involving some pretty big flying machines, a man who wants to rule more than just the ocean, a encounter with the most famous and dangerous pirate of all, a race to get to a lost world (Hint, Hint) and Jack and his crew going to where no pirate has gone before".
So I assume that means Atlantis?
The site's scooper says to expect the film in either 2009 or 2010.
