Weekend Box Office (02/06/11): Roomate tops slow Super Bowl weekend, Sanctum slightly underwhelms, Oscar films continue to soar.

The Super Bowl weekend is not what anyone would consider prime movie-going real-estate, so it stands to reason that there wouldn't be much on the wide-release circuit this weekend. Screen Gems scored their biggest opening weekend ever last Super Bowl Sunday with the romantic drama Dear John, which opened to $30 million and knocked Avatar off the top spot. But generally speaking, Screen Gems's has had pretty decent success opening teen girl-friendly PG-13 horror pictures, often remakes of R-rated 70s and 80s slasher pics, over the last several years, so they went that route again this year. This year's entry, The Roommate, a film so obviously copied from Single White Female that complaints/summons are probably being drafted as we speak.
