Pirates Of The Caribbean: At World's End is to be the last film in the adventure series.
Screenwriters Ted Elliott and Terry Rossio - who also penned the first two films - The Curse Of The Black Pearl and Dead Man's Chest - want the third instalment to be the final movie.
Elliott said: "At World's End is a fairly apt title.
There is the idea of an end of an era - the golden age of piracy coming to a close."
Rossio added: "Certainly with At World's End the tone is different. Like Ted said, there is an epic and of the era feel to it.
