It looks like moviegoers have finally exhausted their supply of Avatar-only interest. Yes, after a sleepy start to 2010 in which new titles were routinely overlooked in favor of Fox’s big, blue behemoth, this weekend’s three debuts have all gotten off to a profitable start; pushing Avatar down to fourth place for the first time since… ever. So far, Friday’s estimates put WB’s Valentine’s Day comfortably in front with $14.6 million – a record debut for a comedy on President’s Day weekend. Meanwhile, fellow newcomers Percy Jackson and the Olympians: The Lightning Thief and The Wolfman were nearly tied on Friday with an estimated $9.7 and $9.8 million, respectively. Expect Percy to pull out ahead by Saturday, however, as the younger generation descends on theatres during this extended four-day weekend.
