According to court records, Rust movie first assistant director Dave Halls handed Baldwin the gun that the actor used to accidentally shoot and kill cinematographer Halyna Hutchins. Before handing Baldwin the gun, Halls yelled "cold gun" to indicate that it was safe to use. Prop maker Maggie Goll says when she worked with Halls on the Hulu anthology series Into the Dark in 2019, alleging that he allowed an unsafe work environment. The job of the first assistant director is to ensure the safety of the set. "He did not maintain a safe working environment," Goll said in a detailed statement to NBC News. "Sets were almost always allowed to become increasingly claustrophobic, no established fire lanes, exits blocked ... safety meetings were nonexistent." Halls has yet to speak out on the Rust incident.
