David Hess was the first choice for Alex because he played a similar villain in The Last House on the Left (1972), which was a highly successful low-budget thriller. The makers of this film wanted Hess involved so much that they gave him half the rights to the film.
In 2006 the BBFC conducted a research study on people's responses to films that included scenes of sexual violence. This film was selected to be examined in the study because of its notorious reputation with the UK censors.
Because Wes Craven's The Last House on the Left (1972) had been such a success, this film, which is similar in violent content and also stars Hess, was given the slightly similar title "The House on the Edge of the Park". It was one of many violent thrillers to be given a "House" title in attempt to ride the success of Craven's earlier film.
The film was initially rejected for a UK cinema certificate by the BBFC when first submitted in March 1981, and later found itself on the DPP list of "video nasties" when it was revealed that the uncut version was readily available on UK video. After it was eventually passed by the BBFC in July 2002, it was cut by 11 minutes and 43 secs, with almost all of the rape and violence either replaced or removed entirely.
