Trivia: You Only Live Twice

  • California Doubling: The underwater scenes are supposed to be Gibraltar, but were shot in the Bahamas; also, since Japan didn't allow for Stuff Blowing Up in a national park, parts of the Little Nellie battle were shot in Spain.
  • The Danza: 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.)
  • Hey, It's That Guy!:
    • Sean Connery has the dubious honor of beating the crap out of The Rock's grandpa, WWE legend High Chief Peter Maiva.
    • Tsai Chin, who plays the MI6 agent Bond sleeps with in the pre-credits teaser, would later play the mother of Ming-Na Wen's characters in both The Joy Luck Club and Agents of S.H.I.E.L.D..
  • The Other Darrin: Donald Pleasence takes over the role of Blofeld from the Anthony Dawson/Eric Pohlmann combo that had previously been playing the part...
  • The Other Marty: ...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.
  • Serendipity Writes the Plot:
    • Mie Hama was having trouble learning English, while Akiko Wakabayashi had much progress. Since the former took this so seriously that she threatened to 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 Sean Connery's height.
  • Throw It In: 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.
