The first trailer for "Gangster Squad," the forthcoming period crime film starring Ryan Gosling, Sean Penn and Emma Stone, included a dramatic scene where characters pulled submachine guns on moviegoers in Hollywood's Grauman's Chinese Theatre.
That scene was cut after real-world violence erupted during a midnight showing of "The Dark Knight Rises" in a Colorado movie theater in July. Twelve people were killed and 58 injured in the mass shooting in Aurora, Colo. "Gangster Squad's" release date was pushed from this fall to next January.
