A scene similar to Kelly's undercover belly dance appeared earlier the same year in Jaime and the King (1977), when Jaime Sommers poses as a harem girl, using a veil to help conceal her identity. The same plot device was also used later in Not Without My Nanny (1998).
Just over two years later, Kelly again escapes through a skylight, in season four's Avenging Angel (1979).
A different version of the Jacques Brel song Olga and Luisi audition to ("If We Only Have Love") had been used previously in the The Vanishing Lady (1973) episode of The Magician (1973), which starred Bill Bixby. Better known as an actor, Bixby also directed numerous television shows, including season one's Dirty Business (1977).
