Leonard Nimoy and William Shatner played together in this show just prior to starting the original Star Trek series. Additionally, Joseph Sargent directed an early Trek episode, "The Corbomite Maneuver."
Madame Kurasov is shown reading a magazine called Elite. Four years later this very same prop magazine would be seen in Star Trek's "Bread and Circuses", where Mr. Spock would come across it in a pile of magazines. This magazine Elite is also shown at the beginning of some episodes of Mission impossible with Cinnamon Carter ( Barbara Bain ) on the cover..
