20 Things You Didn't Know About Diamonds Are Forever (1971)
2. Goldfinger, Part 2
In reminding audiences that James Bond had not lost his Midas touch, the producers looked to Goldfinger for inspiration on how to recapture the British agent’s box office magic, so much so that Diamonds Are Forever was originally conceived as a sequel to the earlier film.
Screenwriter, Richard Maibaum had planned for Goldfinger’s twin brother (also to have been portrayed by Gert Fröbe) to avenge his brother’s death using a laser-wielding supertanker.
However, the license to use SPECTRE and its members, including Ernst Stavro Blofeld, was only valid until 1975. The filmmakers, therefore, decided that, despite the less-than-ideal response to On Her Majesty’s Secret Service, a cap needed to be put on SPECTRE’s long-running role in the franchise so that Double-0 Seven could put the past behind him and move on to pastures new.
Nevertheless, the supertanker plot was loosely adapted in The Spy Who Loved Me (1977).
