Screen Gems scored another number one genre release even if The Roommate’s estimated $15.6m opening haul was not as emphatic as previous launches from the company’s storied past.

Super Bowl weekend is always a time when the US switches to another past-time and the session is traditionally a slow one.

Universal’s caving adventure Sanctum produced by James Cameron debuted in second place on a disappointing $9.2m.

Several Oscar contenders are nearing the $100m mark. The King’s Speech in fourth place stands at $84.1m through TWC while Fox Searchlight’s Black Swan in tenth has grossed $95.9m.

Next weekend’s wide releases are Focus Feature’s action film The Eagle starring Channing Tatum; Buena Vista’s animated film Gnomeo & Juliet; Sony’s rom-com Just Go With It starring Adam Sandler and Jennifer Aniston; and Paramount’s teen doc Justin Bieber: Never Say Never.
