In the scene where Major Amasova couldn't drive stick, Barbara Bach, Anya's actress, actually couldn't drive stick: Moore's snarky responses were unscripted!
Roger Moore decided last minute it would be much more dramatic if he was sitting in the chair instead standing behind it when the gun underneath the dining table was fired. The special effects team had only reinforced the back of the chair for the original planned shot, which meant Moore risked serious injury if he didn't leap away in time.
According to production designer Ken Adam, that was a look of real panic on Barbara Bach's face in the scene where the tunnels of Atlantis are flooding because she didn't expect such a powerful deluge of water.
Fake Russian: Russian secret agent Anya is played by Barbara Bach, an American actress.
The last point is arguable. Beginning with You Only Live Twice, the movies tended to incorporate the setting, a few characters, and (maybe) the general plot of the book while going off in their own direction. It is true that this one was the first Bond film that had NOTHING to do with the source material other than the title, though.
The one thing that is kept is a villain with steel-capped teeth. Though, in the book Sol Horowitz (aka Sol Horror) is described as thin and lizardlike, whereas Jaws is.....well, Jaws.
Stanley Kubrick: Ken Adam asked for his opinion on how to light the enormous set of the interior of Stromberg's supertanker. After being promised that his visit would be a secret, he inspected it for a few hours and suggested using floodlights as part of the set to light the whole thing.
The Red Stapler: After this movie, demand for white Lotus Espirits grew so much that new customers were put on a three-year waiting list.
Throw It In: As above in Enforced Method Acting, Moore's response to Bachman being unable to drive stick were unscripted but left in.
Stromberg was originally going to be Blofeld before the legal rights squashed that idea.
Reportedly, one script draft featured the arrival of a "new" SPECTRE, comprised of former members of various real life terrorist groups. The film would've opened with the new group raiding SPECTRE HQ and killing off the organization's old guard before taking over.
Steven Spielberg was considered to direct, but was rejected because he was thought to be inexperienced.
James Mason was considered to star as Stromberg.
Albert R. Broccoli wanted Lois Chiles to star as Anya, but she was taking a break from acting at the time. She would star as Holly Goodhead in the next movie Moonraker.
The producers thought of bringing Anya Amasova back in A View to a Kill. After Barbara Bach declined, the part was rewritten into another female KGB agent, Pols Ivanova.
Creator Backlash: Fleming hated the book to the point of only selling the title to the producers.
Old Shame: Fleming saw the book as a failed experiment.
