The makers of the 3D dance movie 'Step Up Revolution' have pulled advertising which shows a troupe of dancers entering a room wearing gas masks. The scene has been pulled from promotional footage of the movie, out of respect for those affected by the Dark Knight Rises shootings. On Friday, suspect James Holmes released a canister of gas into a cinema that was screening the movie, before opening fire and killing twelve people. Several more were injured in the incident.

Summit Entertainment has refused to pull the scene from the film entirely, though. The scene, according to Hollywood Reporter, involves a troupe of dancers infiltrating a corporate party. They are wearing gas masks and carrying smoke canisters. In a statement, Summit said "Step Up Revolution is an uplifting film that celebrates the redemptive power of dance. There is a brief scene in the film in which a troop of dancers enter a room wearing gas masks as props and the dancers immediately go into a choreographed routine." The statement continued "because of last week's tragic events in Colorado, Summit immediately removed television advertising that briefly showcased that scene from the film. The scene also briefly appeared in a trailer released three months ago that the studio is no longer actively servicing. Having taken these steps, Summit will open this inspirational, nonviolent film in theatres nationwide this weekend as originally edited."

Step Up 4 is not the only movie to undergo alterations in the wake of last week's events. Warner Bros. is delaying the release of Gangster Squad and may be editing the movie. It contains a scene in which mobsters open fire in a theatre.
