In the film's promotional featurette, actress Jennifer Tilly outlines how in the movie's original script, it called for her character's breasts to pop out in one scene at the race-track during all the excitement of the cheering and rooting for the racing horses. In the end, this does not occur in the finished film, Tilly having suggested that they shouldn't, but they do wobble and jiggle and bounce and significantly project outwards during the particular shot, which is also shown in the promo short.
Star Richard Dreyfuss said of this film in the movie's promotional featurette: "What turned me onto the project was that there was a real music to this script. I don't remember a film that was as densely populated with great eccentric characters and that everyone spoke with a funny eccentric voice".
This 1989 movie was the second of three consecutive filmed adaptations of Jay Cronley novels in three consecutive years produced by Hollywood. The other adaptions were 1988's Funny Farm (1988) and 1990's Quick Change (1990).
Actor David Johansen can be seen wearing a Bushwood Country Club hat from the movie Caddyshack early in the film.
According to Rating the Movies, "the movie was filmed mostly at Florida's Hialeah racetrack". The Hialeah Race Course is located in south Florida and the picture was shot there during the track's off-season. Racing was also conducted at nearby Calder Race Course, and Dreyfuss was spotted on several occasions, presumably researching his role as Trotter. Although this classic track was closed for many years, the facility was reopened in 2009 offering only Quarter Horse racing as opposed to the Thoroughbred Racing that Hialeah traditionally offered.
