Jackass 3D may have grossed out the critics, but it also outgrossed every other movie at the box office over the weekend as it piled up an estimated $50 million, the most ever earned for an October debut. Only one other film even came close -- 2003's Scary Movie 3, which earned $48.1 million. (Some analysts suggested that Jackass 3D 's results for Sunday may have been over-estimated, noting that R-rated films ordinarily take a big hit at the box office on Sundays. On the other hand, no one expected the film to sell as many tickets on Friday and Saturday as it did. Analysts also noted that Scary Movie 3 sold more tickets, given The Rise in ticket prices since 2003 and the 3D surcharge for the latest Jackass. ) Coming in second was RED, the latest comedy thriller featuring aging onetime action stars -- this one headed by Bruce Willis. It earned about $22.5 million -- at the high end of predictions. Meanwhile, The Social Network slipped to third place after holding on to the championship over the previous two weeks. But its estimated gross of $11 million -- just 29 percent below last week's earnings -- also topped forecasts and brought its total after three weekends to $63.1 million. In limited release, Clint Eastwood's Hereafter earned a solid $231,000 at six theaters, auguring well for a big turnout next weekend when it expands nationwide.
