All the Parisian street-names mentioned in the pursuit sequence in this episode are fictitious, and use the surnames of well-known French film directors, including Henri-Georges Clouzot and Francois Truffaut.
The villain of this episode, Guy Gabriel, is the sleazy owner of a lucrative girlie magazine and also of several key clubs. Given that his first and last names start with the same initial, were 1965 viewers meant to think the character was inspired by Hugh Hefner, owner of the "Playboy" empire? Perish the thought!
The island pictured in the title shot is the same island as "Gilligan's Island".
Vincent Gardenia's character is named "Inspector Javert" - a little literary in-joke as Inspector Javert is the implacable police officer in Victor Hugo's classic novel, "Les Miserables".
Dina Merrill guested as the leading lady of this first episode and also was the leading lady of the show's last episode.
In this episode, Alec poses as a reclusive millionaire who uses pseudonyms, never appears in public and never allows himself to be photographed. Although he is said to be Australian, this fake character could hardly fail to remind viewers of the real-life Howard Hughes, who maintained his privacy so stringently that newspapers were said to offer thousands of dollars to any cameraman who could get a picture of him.
