Rachel Mason talks about the tragic on-set accident that led to the cinematographer's death, Alec Baldwin, who fired the gun, and how the film's crew is coping with trauma

Rust and the Story of Halyna Hutchins" director Rachel Mason explains why her all-access film shifted to focusing on her friend's death, what she learned, and why she 100-percent stands by it.

Baldwin called the accident the “worst thing” that has ever happened to him. He didn’t take part in Hulu’s doc about the shooting but footage of him before — and after — the incident was featured in Last Take: Rust and the Story of Halyna.
