In "Shadows of an Afternoon", Michael Conrad was a uniformed policeman, years before he became famous as Police Sgt. Phil Esterhaus on Hill Street Blues. In "Soda Pop and Paper Flags", Alan Alda guest-starred as a surgeon, a precursor to his career-defining role as Dr. Benjamin Franklin "Hawkeye" Pierce on M*A*S*H.

This episode was filmed and set in Niagara Falls, New York, but also features a few shots taken in Niagara Falls, Ontario, Canada.
