The camera operators and their assistants were frustrated by the conditions surrounding the low-budget film, including complaints of long hours and pay, according to three people familiar with the matter who were not authorized to comment.

The camera crew showed up for work as expected at 6:30 a.m. Thursday and began gathering up their gear and personal belongings to leave, one knowledgeable crew member told the Los Angeles Times…

“Corners were being cut — and they brought in nonunion people so they could continue to shooting,” the knowledgeable person said.

There were two misfires on the prop gun and one the previous week, the person said, adding “there was a serious lack of safety meetings on this set.”
