The movie was allegedly intended as a parody of Al Pacino's undercover cop movie Cruising (1980). The 'DVD Verdict' website states that this movie is "basically William Friedkin's Cruising (1980) turned in to a sitcom."
This is the only theatrical movie directed by James Burrows. He has directed numerous television movies.
Before Ryan O'Neal and John Hurt were cast in the two lead roles, two different star teamings were allegedly sought for the movie which didn't eventuate. They were Clint Eastwood & Woody Allen and James Caan & Dudley Moore. Reportedly, these castings didn't materialize apparently due to scheduling conflicts.
This movie was written by Francis Veber, who had just recently penned La Cage aux Folles (1978) and La Cage aux Folles II (1980). Veber described this movie as "a portrait of two men expanding their horizons."
The make, model, and color of the car the two undercover cops, played by Sir John Hurt and Ryan O'Neal, drove was a black-top pink, lilac, and lavender body Volkswagen Beetle convertible.
