Talking with press at the recent trailer launch for “Pirates of the Caribbean: On Stranger Tides”, director Rob Marshall explains the story details a bit further in regards to what we can expect from this fourth film.
“The whole opening and the first third of the film takes place in London. So we start on dry land and there is an impostor that Jack is looking for. He then escapes from the palace, gets captured by King George and there is a huge carriage chase” Marshall tells Movieweb.
He adds “[W]e set sail and that is sort of the second act. it’s a new ship, Blackbeard’s ship, the ‘Queen Anne’s Revenge.’ Then Barbossa has a new ship called the ‘Providence.’ The third act is this incredible jungle adventure through caves where they are looking for the Fountain of Youth.”
He goes on to explain that Barbossa (Geoffrey Rush) has allied himself with the king’s navy this time out, but the pirate still remains underneath.
