Most Hollywood celebrities vehemently supported President Barack Obama’s push to expand existing gun control laws, including the star-studded Demand a Plan video.

The national effort stalled, but New York Gov. Andrew Cuomo’s successful push for new legislation could negatively impact gun-related productions in the state.

Officials in the movie and television industry say the new laws could prevent them from using the lifelike assault weapons and high-capacity magazines that they have employed in shows like “Law & Order: Special Victims Unit” and films like “The Dark Knight Rises….”

Industry workers say that they need to use real weapons for verisimilitude, that it would be impractical to try to manufacture fake weapons that could fire blanks, and that the entertainment industry should not be penalized accidentally by a law intended as a response to mass shootings….

But some lawmakers, feeling stung by conservative and upstate voters over the gun-control law, do not wish to vote on it again, even to make what the industry describes as a technical correction. Gun rights activists, who are challenging the new firearm restrictions in court, have mocked the idea of a so-called Hollywood exception.
