When director William Tannen hired Tangerine Dream to score the film, he told them not to do the end title song because he had one he was using - "Sympathy For The Devil" by The Rolling Stones. Tangerine Dream said it was the perfect song to end the film with. They scored the entire film but this piece. The studio felt the song was too expensive and instead gave the assignment to an assistant who worked for one of the vice presidents. It was voted "worst" end title song for 1984 by the film critic Leonard Maltin.
This was the first theatrical film produced by Home Box Office (in association with Silver Screen Partners).
Because of inflation, $800,000 in 1984 is equal to the purchasing power of just over $2 million in the year 2020. $800,000 in 1963 would be valued at just under $6.8 million.
Some movie posters for the film featured a long blurb that read: "They drink together. Work together. Party together. They live for trouble. Now they've uncovered a secret and their troubles are just beginning."
