"Gangster Squad" may change after Colorado shooting

(CBS News) Warner Bros. is reportedly planning to make changes to its film "Gangster Squad" in wake of the July 20 mass shooting during a midnight screening of "The Dark Knight Rises" in Aurora, Colo.

The movie studio pulled the film's trailer - which included a scene where gunmen open fire through a movie screen into a crowded theater - following the attack, which killed 12 and injured dozens of others. Now, reports say, that sequence could be removed from the film itself.

According to the Los Angeles Times, which cites "knowledgeable people not authorized to discuss the matter publicly," studio executives are considering pushing back the release date and recutting the film to minimize the theater-shooting scene or removing it altogether.

A source also told Entertainment Weekly that Warner Bros. has decided to either cut that scene completely or have it reworked extensively.

The movie theater scene has been described as a pivotal part of the film, which is about the Los Angeles Police Department's fight to keep the mafia out of the city in the 1940s and '50s. Reports note that cutting or altering a key scene might require the film to undergo script revisions and reshoots, which could delay the film's release.

"Gangster Squad," which stars Sean Penn, Ryan Gosling and Emma Stone, is currently scheduled to be released on Sept. 7. E! News reports that a final decision about whether to push back the release date has not been made, but the studio may make an announcement as early as Tuesday.
