Johnny Depp's record-breaking Pirates Of The Caribbean sequel is still afloat at the top of the US box office for a third week, plundering efforts from a string of new releases. DEAD MAN'S CHEST hauled in a treasure trove of $35 million (GBP19.4 million) in its third weekend on release to take its three-week booty to a staggering $321.7 million (GBP178.7 million) in America alone. Animated kids horror movie MONSTER HOUSE debuted at number two with an impressive $23 million (GBP12.8 million) opening weekend take, while M NIGHT SHYAMALAN's spooky LADY IN THE WATER entered the new box office list at number three with a strong $18.2 (GBP10.1 million). Cult movie-maker Kevin Smith's much-anticipated CLERKS sequel netted $9.6 million (GBP5.3 million) to come in sixth, while Uma Thurman's comedy stint as MY SUPER EX-GIRLFRIEND debuted at seven with a disappointing $8.7 million (GBP4.8 million).
