Warner Bros. is moving the release of Gangster Squad to Jan. 11, postponing it from its scheduled Sept. 7 release date in order to accomodate reshoots because of a scene of a movie theater shoot-out in the completed film that became problematic in the wake of the Aurora, Colo. massacre.

The studio announced the release date change late Wednesday. The only other release currently scheduled for Jan. 11 is Paramount's Hansel and Gretel: Witch Hunters, starring Jeremy Renner and Gemma Arterton.

The film, which is based on efforts of the Los Angeles police to control the Mafia in the '40s and '50s, included a climactic gun that was filmed at Grauman's Chinese Theater. The scene could be glimpsed in a trailer for the movie that the studio pulled from circulation on July 20 after the shooting that claimed 12 lives.

Since then, the studio has been holding discussions about how to revise the movie, directed by Ruben Fleischer, written by Will Beall and featuring a large cast, including Ryan Gosling, Sean Penn and Josh Brolin.
