A trailer for the film “Gangster Squad,” which shows four men shooting up a movie theater, has been pulled from theaters after a gunman in the theater killed 12 people and injured dozens more at a midnight screening of “The Dark Knight Rises” in Colorado.

Deadline’s Nikki Finke and the LA Times both report that Warner Brothers asked movie theaters not to play the trailer after the shootings, and that they are rushing to distribute a new trailer that does not feature the scene.

Ryan Gosling, Sean Penn and Emma Stone star in the flick about 1949 Los Angeles mobsters. About two minutes into the trailer, four men hide behind the screen in Grauman’s Chinese Theater in Hollywood, and begin to shoot automatic weapons into the darkened theater as the audience watches the movie. The men shoot through the screen, and then step into the theater and continue to shoot as the panicked audience tries to escape.

There is no word yet on whether or not the film will be edited to alter or remove the scene. “Gangster Squad” is set to open Sept. 7.

See the trailer below — though, it’s likely to be removed from YouTube soon.
