Funnyman Will Ferrell's NASCAR comedy TALLADEGA NIGHTS: THE BALLAD OF RICKY BOBBY has raced to the top of the US box office with a staggering $47 million (GBP26.1 million) opening weekend take. The film, about a clueless racecar driver, led four new entries in the new top 10, but made more money than the remainder of the top five put together. Animated comedy BARNYARD came in a distant second with a $16 million (GBP8.9 million) opening weekend take. Former number ones Pirates Of The Caribbean: DEAD MAN'S CHEST and Miami Vice slipped to three and four respectively. Horror movie THE DESCENT debuted at number five with $8.8 million (GBP4.9 million).
