'Rust' armorer once caused Nicolas Cage to storm off a film set after she repeatedly fired a gun without warning, former colleague says

• "Rust" armorer Hannah Gutierrez-Reed has come under scrutiny after a fatal on-set shooting involving Alec Baldwin.
• According to a colleague who worked with Gutierrez-Reed on "The Old Way," Nicolas Cage yelled at the armorer for firing a gun without warning.
• Neither Cage nor Gutierrez-Reed responded to Insider's requests for comment.

The armorer working on the set of "Rust," where actor Alec Baldwin shot and killed a cinematographer last week, exhibited lax gun safety on the set of another film just two months prior, The Wrap reported.

Stu Brumbaugh, who worked as a key grip on the set of "The Old Way," told The Wrap that Hannah Gutierrez-Reed's behavior caused star Nicolas Cage to scream at her and storm off set.

Brumbaugh said Cage snapped when Gutierrez-Reed fired a gun near the cast and crew for the second time in three days without warning.

"Make an announcement, you just blew my f------ eardrums out!" Cage yelled before walking off the set, Brumbaugh told the publication.

Insider reached out to Brumbaugh and a representative of Cage's for comment on Wednesday, but did not immediately receive responses.

Brumbaugh told The Wrap that he witnessed other examples of Gutierrez-Reed exhibiting poor gun safety.

Brumbaugh said she walked onto set with live rounds of blanks without making a public announcement to cast and crew. She also tucked pistols under her armpits, which ended up being pointed at people when she turned her back to them, he said.

Gutierrez-Reed did not respond to Insider's request for comment on Brumbaugh's allegations.

Brumbaugh said he told the assistant director on the film that Gutierrez-Reed should be fired, and in the process learned that it was her first film.

Insider reached out to the production companies behind "The Old Way" and "Rust" for a reaction to Brumbaugh's comments, but didn't receive a response on Wednesday.

An unnamed producer who spoke to The Wrap contested Brumbaugh's account of Gutierrez-Reed's work on "The Old Way."

"I have no such recollection of this event on our set. I asked my partners the same," the producer said. "The details on some of these accounts specifically when it pertains to 'The Old Way' have been blown out of proportion."
