Nelson Riddle wrote the theme music played at the beginning and end of each episode.
Two of the show's stars--Gig Young and Charles Boyer--committed suicide within two months of each other in 1978.
David Niven (Alec Fleming) and Robert Coote (Timmy St. Clair) played Captain Fritz von Tarlenheim in different adaptations of the 1894 novel "The Prisoner of Zenda" by Anthony Hope: Niven in Le prisonnier de Zenda (1937) and Coote in Le Prisonnier de Zenda (1952).
Cathleen Nesbitt and Robert Coote appeared in the original Broadway cast of "My Fair Lady", as Mrs. Higgins and Colonel Pickering.
TV audiences were disappointed that David Niven did not appear regularly on "The Rogues" but only starred in six episodes. He and Charles Boyer were founders off Four Star Productions and had alternated starring roles with Dick Powell, the other founder, for "Four Star Playhouse" in the early 1950s. By the early 1960s, Niven had an active movie career, leaving Boyer and Young to carry the load in The Rogues. Niven later said in interviews that he starred in the first episode but had never intended to take a very active role in the series.
