Steve Martin and Scott Caan did not get along during filming, due to Caan's reckless behavior toward a stunt person in a scene in which his character smashes a beer bottle over the head of a man in a bar.

The second time Steve Martin plays a dentist. The first time was his role in Little Shop of Horrors (1986), as Orin Scrivello, albeit that character was far more "disturbed" than Frank Sangster.
