A crew member working on the Western movie Rust said in a lawsuit that the script never called for a gun to be fired during a scene that Alec Baldwin was rehearsing when he killed a cinematographer last month. Script supervisor Mamie Mitchell alleges Baldwin should have checked the gun himself for live ammunition rather than relying on the assistant director’s assertion that the Colt .45 revolver was safe to use. “In our opinion, Mr Baldwin chose to play Russian Roulette when he fired a gun without checking it and without having the armorer do so in his presence,” Mitchell’s attorney Gloria Allred told a news conference.
