A gun regulation bill Hollywood hopefuls were counting on has been denied by California state legislature. According to the Directors’ Guild of America and the International Alliance of Theatrical Stage Employees, who released a joint statement in wake of the news to relay their disappointment, this is namely due to the lack of support from the studios.

The proposal was first introduced in response to the tragedy that took place on the Rust set last October in New Mexico, where cinematographer Halyna Hutchins lost her life after a real bullet was fired on set. This bill would have made any live ammunition on set forbidden without the proper trained armorer as well as required all employees “handling or in proximity to” any firearms to take a course in gun safety. The document also proposed a professional be on set at all times to calculate the risk of the firearm stunts. Lastly, it would have required all employers to report any occasions involving firearms or ammunition during production.

These two unions aren’t the only ones fighting for gun safety in Hollywood. In addition to the numerous stars who have spoken out since last October, the Motion Picture Association has also been outspoken about making change in the film and television industries. MPA has been outspoken in support of another bill, SB 829, regarding gun control which also did not make it through California legislature.
