�Pirates of the Caribbean: At World�s End� was number one at the box office for just two weeks, as the Brad Pitt/ George Clooney caper movie �Ocean�s 13� has taken the top spot stateside.

The crime- comedy, which also stars Al Pacino, Matt Damon and Bernie Mac, made in excess of $37million and hammered the Pirate movie despite being released in 500 fewer screens across the US.

Disney can, however, take solace in the fact that this kind of slump is expected (although not this early) and that the film�s international haul will be sure to bump up the $250million it has made domestically.
