Aside from Marc Lawrence's original cut of the film, which was titled "The 13th Pig", two other versions of the film exist. One featured a three minute introduction depicting Toni Lawrence's character (portrayed by a different but similar looking woman) being possessed and the subject of an exorcism, ending with her bolting from the room. This version was exhibited under the title "Love Exorcist" and also "Blood Pen". A second version of the film features a new intro that shows Lynn's childhood experiences with her incestuous father, ending with her stabbing him to death and being committed to an asylum; she escapes when a nurse undresses to have sex with a doctor, leaving behind her uniform and her car keys. There is also a new ending in this version, which shows Lynn faking her own death and escaping once again in her car. Lynn is portrayed in these additional scenes by various actresses wearing wigs, photographed from obscure angles. This version of the movie was originally titled "Daddy's Girl". This is also the cut that was released to home video under various titles, including "Pigs", "Horror Farm", "The Killers" and "Daddy's Deadly Darling".
