This two part episode is a sequel to "The King Lives?" from last season. The take-off of the movie "The Prisoner of Zenda" continues as Max once again switches places with his lookalike king (ala Ronald Colman) and James Caan appears as a swashbuckling villain inspired by the Rupert of Hentzau character played by Douglas Fairbanks Jr.
James Caan is not credited in this episode. The end titles read "Rupert of Rathskeller as Himself".
Episode Title: To Sire, With Love
The title is a pun based on the 1967 movie To Sir, With Love starring Sidney Poitier and based on the book by E.R. Braithwaite.
