The film was a remake of the 1976 two-part TV movie.

During the murders committed in 1958, Starkweather was accompanied by his 14-year-old girlfriend, Caril Ann Fugate.

They gained national notoriety after the infamous murder of actress Sharon Tate and four others on August 9, 1969 by Tex Watson and three other members of the Family, acting under the instructions of Charles Manson. Group members were also responsible for a number of other murders and assaults, and the attempted assassination of President Gerald Ford.

Manson and his followers committed a series of nine murders at four locations in California, over a period of five weeks in the summer of 1969. Known within the Manson family as Sadie Mae Glutz or Sexy Sadie, Atkins was convicted for her participation in eight of these killings, including the most notorious, the "Tate/LaBianca" murders. She was sentenced to death, which was subsequently commuted to life in prison. Atkins was incarcerated from October 1, 1969, until her death – a period exactly one week short of 40 years. At the time of her death, Atkins was California's longest-serving female inmate.

Manson's followers committed a series of nine murders at four locations in July and August 1969. In 1971 he was found guilty of first-degree murder and conspiracy to commit murder for the deaths of seven people – most notably of the actress Sharon Tate – all of which were carried out by members of the group at his instruction. Manson also received first-degree murder convictions for two other deaths. Manson was originally sentenced to death, but his sentence was commuted to life imprisonment when California invalidated the state's death penalty statute in 1972. He is currently serving multiple life sentences at California State Prison in Corcoran.
Document 9: Helter Skelter (album): Helter Skelter is the second studio album by The D.O.C.; released on January 23, 1996. This album was an attempt at making a comeback following the car crash which severely damaged his vocal cords. The album was widely ignored, and has even been discredited by D.O.C himself. The name of the album is a reference to Charles Manson's idea of The Beatles' "Helter Skelter" prophesying the end of the world.

Document 11: Leslie Van Houten: Leslie Louise Van Houten (born August 23, 1949) is an American murderer serving a life sentence in relation to the 1969 killings of Leno and Rosemary LaBianca, when Van Houten was 19 years old. She was arrested weeks later, and convicted at the main Charles Manson trial in 1971, at which she repeatedly sabotaged her own defense, and tried to exculpate Manson. She was convicted and became the youngest woman ever sentenced to death in California. However, executions were halted in the state in 1972 after the California Supreme Court ruled that the death penalty was unconstitutional in "The People of the State of California v. Robert Page Anderson", 493 P.2d 880, 6 Cal. 3d 628 (Cal. 1972). She was granted a new trial at which her defense to the charge of first degree murder was diminished responsibility, but the jury could not agree on a verdict. At a third trial, she was convicted and sentenced to life in prison, although with a possibility of parole. In relation to her case, high courts, parole boards, and the state governor have said that an inexplicable or racial motive for murder could merit exemplary punishment and outweigh any evidence of subsequent reform.
Document 12: The Stunt Man: The Stunt Man is a 1980 American film directed by Richard Rush, starring Peter O'Toole, Steve Railsback, and Barbara Hershey. The movie was adapted by Lawrence B. Marcus and Rush from the 1970 novel of the same name by Paul Brodeur. It tells the story of a young fugitive who hides as a stunt double on the set of an anti-war movie whose charismatic director will do seemingly anything for the sake of his art.
Document 13: Helter Skelter: L.A. Art in the 1990s: Helter Skelter: L.A. Art in the 1990s, named after The Beatles' song that motivated Charles Manson, was a contemporary art exhibition held from January 26, to April 26, 1992 at the L.A. Museum of Contemporary Art. Organized by Paul Schimmel, "Helter Skelter" displayed the work of 16 artists. Featuring works of sex, violence, and warped Americana, the exhibition aimed to destroy stereotypes of L.A. art and challenge the New York school. At the time "Helter Skelter" was hailed as the prime example of modern contemporary art and is still held as one of the most important and influential contemporary art exhibits in recent years.
Document 14: Tex Watson: Charles Denton "Tex" Watson (born December 2, 1945) is an American murderer who was a central member of the "Manson family" led by Charles Manson. On August 9, 1969, Watson and other Manson followers murdered pregnant actress Sharon Tate and four other people at a house in Benedict Canyon, Los Angeles. The next night, Watson traveled to Los Feliz, Los Angeles, and participated in the murders of Leno and Rosemary LaBianca, as part of Manson's "Helter Skelter" vision. Watson was found guilty of murder and imprisoned in 1971.
Document 15: George Spahn: George Spahn (February 11, 1889 – September 22, 1974) was a rancher who once owned the Spahn Ranch near Chatsworth, Los Angeles, California. Spahn (as did previous owner William S. Hart) rented the ranch to the movie industry to film Westerns. At the ranch, he housed Charles Manson and his followers. The 1969 murders of actress Sharon Tate and six others by Manson's devotees were allegedly hatched at the Spahn Ranch. Manson persuaded Spahn to permit "the Family" to live at his ranch. Manson ordered the Family women to have sex with the then nearly blind 80-year-old. The women also acted as seeing eye guides for Spahn. Spahn nicknamed all the Manson girls—Squeaky, Sadie Mae, Ouisch, etc. According to Manson Family member Paul Watkins, notorious Mansonite Lynette "Squeaky" Fromme got her nickname because of the sound she made when Spahn ran his hand up her thigh. Family member Charles Watson has written that his own nickname, "Tex", was given to him by Spahn, who recognized his Texas accent.
