British author of the source play David Hines had worked as a London cabdriver, and based his play on the stories he heard from prostitutes working the King's Cross area of the English capital. The film is relocated to Los Angeles. British paper The Daily Telegraph, in its obituary of director and co-screenwriter Ken Russell, claimed that Hines was poorly treated by Russell and that when he attended the premiere found that there was no seat for him.
The surly Maitre D played in the restaurant by a credited 'Bob Prupas', appears to have the same voice - and mannerisms - as the film's director, Ken Russell, himself.
In one scene of the film, a clip from High Stakes (1989) is shown. Amos Kollek, writer/director of High Stakes, went on to direct Whore 2 (1994).
During the sequence where Liz brings the injured prostitute into the movie theater bathroom, the marquee outside advertises The Lair of the White Worm (1988), one of director Ken Russell's previous films.
