Alec Baldwin

And in Lane's letter, he writes about his concerns regarding their housing.

He also lays out some safety concerns, saying, during the filming of gunfights on this job, things are often played very fast and loose.

So far, there have been two accidental weapons discharges.

It was, you know, close to nine o'clock when these emails started rolling into the production office that they were gonna be without the camera crew.

for a group of crew members to come together and say, we need to, as a group, basically strike this set.

It's not that common.

This week, 25 members of Rust's cast and crew released a letter that Alec Baldwin posted on his Instagram, which they say was not sanctioned or influenced by the producers.

And it stated, the descriptions of Rust as a chaotic, dangerous, and exploitive workplace are false.

In response to Lane Looper's allegations, the production team from Rust told ABC News that Mr. Looper's allegations around budget and safety are patently false.

And they say safety is always the number one priority in our films.

The next morning, their departure would be the beginning of a deeply troubling day on set.

The day got off to a bad start.

Most of the camera crew packed up their gear and they walked off the job.

They were making good on the threats from the night before, quitting over their concerns, which included accommodations and safety on the set.

I was as surprised as everybody else when, for the first hour and a half, there was no camera crew on set at all.

I know that that put a little bit of a strain on the whole production.

The first person I saw was Helena, and she didn't look, she wasn't her usual, you know, calm, focused, cheerful self.

She was under pressure to not look stressed, to keep everything rolling.

And shortly after that, there is a safety meeting that did address that there was gonna be, you know, gunfire happening that day.

So before lunch, there was a scene where there were some guns being used.
