Like many of us, Rob Zombie has an almost obsessive interest in Charles Manson, the most fascinating figure in true crime history. Manson’s influence is all over Zombie’s work, so we can’t think of a better person to narrate a documentary about his evil deeds.

Airing this Sunday night, December 3 on REELZ, Charles Manson: The Final Words began filming one year ago. As Manson is now dead, the doc will indeed be his final words, recorded from recent phone calls between Manson and the filmmakers.

“Narrated by musician and director Rob Zombie, the documentary focuses on the Manson family murders told from Manson’s perspective using never-before-seen case files, pictures and exclusive interviews with Manson himself from inside California State Prison.

Charles Manson: The Final Words includes Manson’s eerie and disturbing conversations about modern society, justice, his decades behind bars, the Bernard Crowe shooting and the murders along with digitally restored audio recordings from the original investigations to reconstruct a path of events that led to the brutal slayings of movie star Sharon Tate and four of her friends on August 8, 1969 in addition to the murders of Gary Hinman and Donald “Shorty” Shea.

The documentary also includes compelling new interviews with members of the Manson family which reveal never-before-heard details that help uncover the real story and motives behind the grisly murder spree. Viewers will hear from accused Manson family members Bobby Beausoleil, Barbara Hoyt and Catherine “Cappi” Gillies along with prosecutor Stephen Kay, defense attorney Gary Fleischman, music producer Phil Kaufman as well as other investigators and authors.”
