Despite the graphic gore effects of slasher films being the driving force behind their box office success, the MPAA gave in to the critical reception and reaction of pressure groups who were protesting the films in the wake of violent acts, such as the assassination of John Lennon, and the growing debate about violence in the media. "The Burning" was heavily trimmed to receive its R-rating. The film remained cut in the United States for nearly 30 years, until its release on DVD in 2007 restored the scenes of gore.
