* TheDanza: Aki is played by Akiko Wakabayashi. The character, formerly "Suki," was renamed at her request. (Mie Hama had been supposed to play this role until she was given a part that better suited her limited grasp of English.)
* ExecutiveMeddling: Producer Harry Saltzman hired Jan Werich to play Blofeld without consulting director Lewis Gilbert or fellow producer Albert Broccoli, an example of the increasingly eccentric decisions that eventually helped force him off the series.
* TheOtherDarrin: Creator/DonaldPleasence takes over the role of Blofeld from the Anthony Dawson/Eric Pohlmann combo that had previously been playing the part...
* TheOtherMarty: ...however, he wasn't the first person who attempted to do so. The original actor they cast was Jan Werich, who proved completely wrong for the role and so was replaced by Pleasence. In the final cut, many of Blofeld's scenes prior to TheReveal still feature Werich, as only his hands and legs are visible, meaning that all they needed to do was have Pleasence overdub his dialogue.
* SerendipityWritesThePlot:
** Mie Hama was having trouble learning English, while Akiko Wakabayashi had much progress. Since the former [[SeriousBusiness took this so seriously]] that she threatened to [[{{Seppuku}} kill herself]] if fired (she was afraid of dishonoring her family), the producers just traded the roles between actresses, as Kissy appears much later in the story and has fewer lines.
** The Toyota 2000GT wasn't supposed to be a convertible, but it got converted into one due to Creator/SeanConnery's height.
* ThrowItIn: While everyone else is remarkably calm, Blofeld's cat gets completely freaked out and tries to escape when the control room starts taking structural damage.
* WhatCouldHaveBeen: Creator/ToshiroMifune was considered for Tanaka, but he was busy with ''Film/GrandPrix''.
* YouLookFamiliar:
** Burt Kwouk makes his second appearance in an EON Bond movie as a Japanese SPECTRE operative (he was in ''Film/{{Goldfinger}}'' as Mr. Ling)
** Charles Gray would later play Blofeld in ''Film/DiamondsAreForever''.
** Tsai Chin, who plays the girl Bond sleeps with in the opening teaser, played one of Bond's poker adversaries in ''Film/CasinoRoyale2006''.
