“Then, an explosion,’’ the supervisor, Mamie Mitchell, recalled at a news conference in Los Angeles.
Then, she said, she turned and saw the film’s cinematographer, Halyna Hutchins, sink down to the ground.
21 on the set of the film on Bonanza Creek Ranch in Santa Fe County, N.M., as Mr. Baldwin prepared to film a close-up of him drawing a .45 revolver from a shoulder holster.
According to court papers filed by the Santa Fe County Sheriff’s Department, the movie’s first assistant director, Dave Halls, had called out “cold gun” before handing the revolver to Mr. Baldwin, using a term indicating that the gun did not contain live ammunition.
The lawsuit charges that Mr. Baldwin knew that it was typical protocol for an armorer or prop master to hand a gun to the actor after demonstrating that it is empty — not for the first assistant director to do so — and that Mr. Baldwin failed to follow those rules.
Ms. Gutierrez-Reed’s lawyer, Jason Bowles, has said that his client noticed that day the gun was left unattended for several minutes after she had asked other crew members to watch the firearms and ammunition.
Mr. Halls, Ms. Gutierrez-Reed and Sarah Zachry, the movie’s prop master, are all named as defendants in Ms. Mitchell’s lawsuit.
Last week, Serge Svetnoy, the film’s gaffer, or chief lighting technician, filed a lawsuit accusing the movie’s producers, Mr. Baldwin and several other crew members of failing to follow appropriate firearm safety protocols that would have prevented the fatal shooting.
