Matthew Mcconaughey and Sarah Jessica Parker's critically-slammed new romantic comedy FAILURE TO LAUNCH has rocketed to the top of the US box office with a $24.6 million (GBP14.5 million) opening weekend take. The film beat family movie The Shaggy Dog to the top spot. The Tim Allen comedy debuted at number two with a $16 million (GBP9.4 million) take. Gruesome horror remake The Hills Have Eyes debuted at number three on the new chart with a three-day take of $15.5 million (GBP9.1 million). Last week's box office number one, Tyler Perry's MADEA'S FAMILY REUNION, slipped to number five on the new chart after two weeks at the top.
