ALBANY — The sweeping gun control measure signed by Gov. Andrew M. Cuomo and hailed by Democratic leaders has a surprising critic: Hollywood.

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.”

Twenty-seven film and television projects, including programs like “Blue Bloods” and “Person of Interest,” are now in production in New York State using assault weapons and high-capacity magazines, according to the Motion Picture Association of America. 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.

“Weapons are part of our history as a culture as humans,” said Ryder Washburn, vice president of the Specialists Ltd., a leading supplier of firearms for productions that is based in Manhattan. “To tell stories, you need them.”
