According to the film's producer, director, writer and star Marc Lawrence, at its theatrical premiere in Detroit, Michigan on May 23, 1973 the distributor offered free bacon to the audience as part of a promotion for it, most of which was quietly and cautiously returned after the viewing of it was finished.
Charles Bernstein did the score for the film in exchange for an oil painting that Marc Lawrence owned.
Marc Lawrence made hunks of bread in the shape of human arms, hands and legs for all of the scenes in the film in which the pigs eat human flesh.
Marc Lawrence put up a second mortgage on his house in order to raise the money that he needed to finish this film.
The film was made in eight days.
