Mimi Craven, Wes Craven's wife at the time, cameos as Nurse Cooper. She also played a nurse in Craven's most well-known film, A Nightmare on Elm Street (1984).
Some copies of the film show the doctors in green scrubs during the surgery; others show them in blue scrubs.
The building shown to be the location of the family company is also the same as shown in Barnaby Jones.
