If Eon Productions were MI6, then Albert "Cubby" Broccoli would be its M. The man behind Eon Productions was responsible for making sure Bond's latest missions went off without a hitch.
But Goldfinger had a major hitch before the mission was even delivered to Bond.
After a dispute with Eon over salary, Terence Young, who directed the first two Bond films, refused to return for a third. Perhaps Eon was running short on funds, having already promised a heftier salary to Connery in order to convince him to don Bond's tux once again. The producers recruited Guy Hamilton, the dude they wanted to direct Dr. No years before. This time, Hamilton became Dr. Yes and took up residence in the director's chair (source).
But a producer's job is never done. Even with a major star and a director, Broccoli and his partner Harry Saltzman had to wrangle with the distributor, United Artists, over a major character's name. No, they didn't want to rename Goldfinger Silverfinger. They were wringing their hands over the name Pussy Galore.
United Artists wanted to rename the character Kitty Galore, so Eon's publicist, Tom Carlile, arranged a meeting with Miss Galore herself, Honor Blackman, and none other than Prince Philip, husband to Queen Elizabeth II. The Daily Mail ran a photo of the two titled "Pussy and the Prince." When no one was outraged over that headline, Eon was able to convince UA to keep Pussy in the picture (source).
Finally, in an effort to appeal to American audiences, Eon decided to set major scenes in the US of A, thereby allowing Yankees to see Bond in Miami, at Fort Knox, and this close to a KFC (source). Even though Bond himself is never seen chowing down on a bucket of the Colonel's extra crispy, Americans found Goldfinger to be finger-lickin' good.
