AceShowbiz - The key gaffer who nursed cinematographer Halyna Hutchins in his arms as she died on the set of troubled movie "Rust" has filed suit against the film's star Alec Baldwin, armourer Hannah Gutierrez-Reed, and assistant director Dave Halls.

Serge Svetnoy claims the defendants' alleged negligence caused him severe emotional distress following last month's (Oct21) fatal shooting incident in Santa Fe, New Mexico.

According to documents, obtained by TMZ, Svetnoy suggests the bullet that struck both Hutchins and director Joel Souza almost hit him too.

He caught Hutchins as she fell and attempted to comfort her and keep her conscious.

Svetnoy is suing Baldwin, who fired the gun believing it was full of blanks, claiming the actor and producer "owed a duty to the Plaintiff and other crew members and actors on the Rust set to handle the Colt Revolver provided to him by defendant Halls with reasonable care and diligence for the safety of Rust cast and crew..."

"This duty called for Defendant Baldwin to double-check the Colt Revolver with Halls upon being handled to ensure that it did not contain live ammunition...," the suit reads. "This duty further called for him to handle the Colt Revolver as if it was loaded and to refrain from pointing it at anyone."

In his suit, the key gaffer also notes that the scene Baldwin was rehearsing when the fatal shot was fired did not call for him to pull the trigger, just draw a gun and point it in the general direction of the camera.

Svetnoy takes aim at Baldwin and his fellow producers, claiming they "attempted to save money by hiring an insufficient number of crew members to safely handle the props and firearms."

He is asking for damages and a jury trial.

Meanwhile, a criminal investigation is still active in Santa Fe, with the city District Attorney revealing several live rounds were found at the location, but adding claims of sabotage by disgruntled crew members seem unlikely.
