life is CHEAP". Shackleton put out false newspaper clippings that reported a citizens group's crusading against the film, and hired people to act as protesters to picket screenings. Shackleton's efforts succeeded in generating a media frenzy about the film: real feminist and citizens groups eventually started protesting the movie and picketing theaters.David A. Cook, Lost Illusions: American Cinema in The Shadow of Watergate and Vietnam, page 233 (University of California Press, Ltd., 2000). As a result, New York District Attorney Robert M.

Rumors related to serial killers and other controversies In subsequent years, more urban legends emerged about snuff movies. Notably, multiple serial killers were rumored to have produced snuff films: however, no such videos were proven to exist. Henry Lee Lucas and his accomplice Otis Toole claimed to have filmed their crimes, but both men were "pathological liars" and the purported films were never found. Charles Ng and Leonard Lake videotaped their interactions with some of their future victims, but not the murders. Lawrence Bittaker and Roy Norris made an audio recording of their encounter with one victim, though not of her death. Likewise, Paul Bernardo and Karla Homolka made videos of Bernardo sexually abusing two victims, but did not film the murders. In all those cases, the recordings were not intended for public consumption and were used as evidence during the murderers' trials. Over the years, several films were suspected of being "snuff movies", though none of these accusations turned out to be true.

To film the scene, a camera was tied to a balloon with ropes attached to prevent it from flying away. Minutes after they started filming, the ropes snapped and the balloons and camera flew away; after traveling over 200 miles, the contraption landed on a farmer's field in Michigan. The farmer later handed it to the FBI, who began investigating whether the footage was a snuff
