Paul Blart Mall Cop , a movie that many critics regard as the year's biggest overperformer, has managed to surprise again on video. The relatively low-budget Sony film, which grossed an astounding $146.3 million domestically earlier this year, has pushed its way to the top of the Nielsen VideoScan First Alert sales chart and also head Home Media Retail magazine's rental chart for two consecutive weeks. Twentieth Century Fox's Taken placed second and the Lionsgate comedy New in Town , third in sales.
