The one with Pussy Galore, Oddjob and the titular Goldfinger attempting to blow a nuke on Fort Knox to irradiate the gold and make all other gold more valuable.
On this film, Bond is dragged around by the villains for too long. He is treated as a guest and practically does not contribute to the plot. The villain’s plan is “now” dated, since the gold standard was abandoned(this was 7 years after the film’s release).
He still gets to screw many women. The Pussy Galore case is borderline curing lesbianism by enforced kissing and implied sex in the hay. It’s really creepy.
I still think the theme song refers to Bond himself, since in the latest film the Tatiana became a political refugee and she doesn’t even get mentioned here.
