James Doohan, who plays Ed the deputy guarding the door of the hotel room, a year after this episode aired would join the cast of Star Trek (1966) and take on what became perhaps his most famous role as Ensign "Scotty" Scott of the U.S.S. Enterprise. This is his first of two appearances in the series, the second appearance occurring in Middle of a Heat Wave (1965).
First of three guest star appearances by Edward Asner. Second of three for John Milford, although, unlike Edward Asner, he did not go on to greater stardom.
This is the second of three appearances John Milford makes in the series, each time appearing as a different character. The other two appearances occur in Smoke Screen (1963) and Joshua's Kingdom (1966).
