Disney head honchos have revealed that though the third 'Pirates' film will conclude the trilogy, it was "unlikely" that it will be the last sequel of the mega-hit movie.

Mark Zoradi, president of the Disney Motion Pictures Group said that the eagerly awaited third movie may not be the last Pirates film.

"The third film... will conclude the initial Pirates trilogy, though it is unlikely to be the last Pirates sequel," the Daily Mail quoted him, as saying.

With the second movie in the series, Pirates of the Caribbean: Dead Man's Chest, become the third film to passing the 1 billion dollar mark at the worldwide box office, bosses have decided to globally release the third and final flick in the series on 25 May 2007, rather than a gradual worldwide release.
