I would argue that
Goldfinger was the most influential film of the last half-century. Goldfinger set the template for future Bond films: start with geek wet dream techno-toys from Q, garnish with unobtainable luxury, add a psychotic super-villian antagonist, and serve on a bed of Bond girls in a heterosexual reduction sauce.
The producers quickly realized that this formula: power, sex, luxury, violence and geek toys have a pretty universal appeal. It not only has sustained the bond franchise for 50 years, but become the most common international movie success template. 007 is like a cinematic Cole Porter: a jazz standard that artists perpetually riff off.
Bond was the perfect western world archetype for the Cold War: the aesthete iconoclast versus the stoic conformer. The problem was: how do keep making larger than life larger than life? (In one Ian Fleming novel there was a Texan who had the windshield of his Cadillac convertible ground to his eyeglass prescription so he could drive without wearing glasses.)
Years ago, I saw
Moonraker (Mission Espacial) in Mexico. The film was in English, with Spanish subtitles. At one point, a character said "You're full of s***". The Spanish subtitle translated this as "You exaggerate too much". It turns out he was right. Moonraker was the apogee of the exaggerated, over-the-top Roger Moore era. You could imagine Mike Meyers as Austin Powers in the same movie without too much trouble.
Over the years Bond has slowly morphed from the consumptive bon-vivant of Sean Connery to the excessive parody of Roger Moore back to a more grounded but somewhat gloomily obsessive Daniel Craig. As Bond has become less British and more international, he seems to have less fun in life. I'll probably see Skyfall. I like Daniel Craig.. But I think 007 has morphed into a character Ian Fleming would have a hard time recognizing. Perhaps that is a testimony to the strength of 007: he has become such an indispensable icon to our Western world of excess that he has become a function of what we want rather than who he is.
