Kim Henkel initially wrote this film as a sequel to his original Non aprite quella porta (1974), before re-writing it to become a stand alone film.
This movie contains more cameo appearances by "Texas Chainsaw" alumni than any other film. There are a total of nine: Perry Lorenz, Edwin Neal, Marilyn Burns, Ed Guinn, Bill Wise, John Dugan, Teri McMinn, Bill Johnson, and James Bargsley.
Several scenes were shot at original movie locations from other films including: Non aprite quella porta - Parte 2 (1986) (Montopolis Bridge, Austin), The Newton Boys (1998) (Peacock Alley, San Antonio), The Hot Spot - Il posto caldo (1990) (downtown Taylor, Texas), Chi tocca il giallo muore (1980) (Hays Street Bridge, San Antonio), and Slacker (1990) (MLK Bridge, Austin). One of the film's directors, Duane Graves, has made a hobby of photographing hundreds of movie locations around the world as they appear today.
The radio news voice heard at the start of Kim Henkel's Butcher Boys is the same one heard at the start of his original Non aprite quella porta (1974). Although uncredited in the 1974 film, the voice belongs to Levie Isaacks, who also served as cinematographer for Henkel's Non aprite quella porta IV (1994).
Based on Jonathan Swift's satirical essay 'A Modest Proposal' published in 1729.
