Overall, the US Box Office was down 5.2% on last weekend's gross.

The September doldrums continue at the box office with the overall weekend gross of the Top 12 down further on last weekend's lowish score. The number one film did some decent business in the return of Tyler Perry with I CAN DO BAD ALL BY MYSELF. Virtually replicating his previous successes to a tee, the film earned a solid $23.4M. Tyler Perry is in effect a cottage industry now, churning out moderate winners on a consistent basis.

Opening in second is the unusual animated flick for adults 9, which managed a decent $10.7M. Based on a successful short film, this feature version cost around $33M to make, but it may struggle to get there with this opening.

The other new openers for this weekend barely caused a stir in SORORITY ROW (in sixth place with $5.5M) and WHITEOUT (in seventh place with $4.1M)). The former is proof that just because a film is horror does not mean legions of people will show up to it, particularly if it is really bad as this film apparently is. The latter, a thriller set in Antarctica received even worse reviews despite starring the lovely Kate Beckinsale. Both films should tank appropriately and disappear without a trace shortly.

The returning films did not carry over much business this weekend, leading to the overall depressed nature of the box office.

The Top 12 at the US Box Office took in a total of $76,901,812 for the whole of the weekend 11-13 September 2009.
