Alec Baldwin Gun Accident 911 Call, 'We Need Help Immediately'

Crew members on the set of "Rust" were quick to dial 911 after a gun accident that left one woman dead, telling operators "we need help immediately."

The caller is the film's script supervisor, and it's clear to hear the panic in her voice when she says 2 people were accidentally shot by a prop gun. The operator asks if a real bullet was fired from the gun, but the caller does not know what shot out.

The newly released call also gives some insight as to how people were shot, telling the dispatch it was during a rehearsal that the gun went off ... she does not know how serious the bleeding on either victim is.

Eventually, a male takes over the call from the film set, and let's the operator know both people are alert and a medic is tending to them ... but clearly, things took a turn for the worse.

As we reported, Alec Baldwin pulled the trigger on the gun, which caused the accident ... 42-year-old Halyna Hutchins died at the hospital after being airlifted and Director Joel Souza was also struck, but was reportedly released from the hospital.

Baldwin released a statement Friday, saying, "There are no words to convey my shock and sadness regarding the tragic accident that took the life of Halyna Hutchins, a wife, mother and deeply admired colleague of ours. I'm fully cooperating with the police investigation to address how this tragedy occurred."

He continued, "I am in touch with with her husband, offering my support to him and his family. My heart is broken for her husband, their son, and all who knew and loved Halyna."

There have not yet been any arrests from the incident, and it continues to be investigated by the local sheriff, district attorney and OHSB.
