Top 10 at the Weekend Box Office

Notes:

• Despite consistently poor reviews, Sony/Screen Gems' thriller The Roommate topped the weekend box office -- grossing an estimated $15.6 million in its debut.
• Despite the extra bump from higher-priced 3D tickets and James Cameron as executive producer, Sanctum couldn't crack the $10 million mark in its debut. However, its $9.2 million opening gross was better than Universal anticipated -- and good enough for #2.
  
• Last week's #1, New Line/Warner Bros.' The Rite, slipped to #6 in its second weekend -- a steep 62% decline.
  
• Though a solid start for The Roommate, the overall box office was down more than 23% from 2010, when Screen Gems' Dear John opened to an especially good $30.5 million. Usually, Super Bowl weekend is hard for Hollywood, with theater traffic dropping substantially on game day.
