Olivia Mela, who appears as the girl in the purple bikini in "Overture" and the title sequence, appears here as well, three times, twice in a bikini, fleetingly in the Cannes swimming pool, seen from afar, and then as one of the lovely passersby in close-up. Soon after, she is the girl on the moped almost running Danny over outside the bank. She doesn't speak English, which is why she couldn't land a bigger part.
Tony Curtis and Larry Storch, playing close friends in "Angie,Angie", were very close friends in real life as well, serving together on the USS Proteus (submarine tender) during WWII, appearing in numerous films alongside each other.
In the room where the men play snooker there is a photo on the wall of Freddie Jones.
At the end of the episode, Danny Wilde (Tony Curtis) made a quip about Lord Brett Sinclair's (Roger Moore) lucky number being Five (5), but Sinclair corrected him that it's actually Seven (7). Roger Moore became James Bond whose codename was 007, and also made Seven (7) Bond films (Live And Let Die, The Man With The Golden Gun, The Spy Who Loved Me, Moonraker, For Your Eyes Only, Octopussy and A View To A Kill).
