Helter Skelter is a 2004 television film written and directed by John Gray, based on the 1974 non-fiction book by Vincent Bugliosi and Curt Gentry about the murders of the Manson Family. The film is the second film to be based on the Charles Manson murders, following the 1976 two-part TV movie of the same name. Unlike the 1976 version, which focused mainly on the police investigation and the murder trial (as did the book), this version focused mainly on Linda Kasabian's involvement with the Manson Family and their development.
