The entire soundtrack to the film is from composer Gustav Mahler's "Symphony No. 6 in A minor- Tragic".

Emmy Award-winning actress Doris Roberts (best known for TV's Everybody Loves Raymond) plays the role of Bunny, Martha's friend who innocently submits Martha's name to the "lonely hearts" club.

The role of Martha Beck was probably actress Shirley Stoler's most well known part. She went on to play another memorably villainous character in Lina Wertmuller's Seven Beauties (1975), in which Stoler played a grotesque Nazi commandant. The actress would later play bit part character roles in various films like Desperately Seeking Susan (1985), Frankenhooker (1990) and Miami Blues (1990). Her most curious appearances would be as Mrs. Steve, a recurring role on the Saturday morning live-action show, Pee-wee's Playhouse!

French director Francois Truffaut said The Honeymoon Killers was "his favorite American film."

This is director Leonard Kastle's sole directorial attempt. To date, this is the only film he has made.

Two separate rock bands called The Honeymoon Killers, one based in New York City, the other in Belgium, were named after the film.
