This is a piece of the 911 call by the script director or writer. At about 50 seconds in, it seems like she thinks she is in hold. She is talking to someone else and casting blame for the gun. She is useless on the phone with the operator but she sounds like she is used to “phrasing” things.

Yeah, that sounded like some backstage chatter with someone standing next to the caller. In my brief experience with local amateur theater I quickly learned there was as much drama offstage as onstage. Some was justified, some not so much. I suspect movie production is not all that different, just more money riding on the outcome. “Hollyweird” is more than a description —for many an actual state of mind.
