Enforced Method Acting: The actor who played Oddjob was more of an athlete than an actor, and did not master the cinematic art of pulling back one's blows. When he injures James' neck in one scene, Sean Connery was actually hurt, and his discomfort was real.
Also, during the infamous laser scene, the special effects team (positioned beneath the table, using a flamethrower to guide the laser light) did not stop torching the laser where they intended. Connery's visible distress is genuine, and he complained when shooting was over.
And finally, a mook is splashed with scalding hot water early in the movie, and was actually burned.
I Spy The American Television series referenced the then currently first-run movie in the episode "So Long Patrick Henry". Spy Kelly Robinson was upset at his partner Scott Alexander hiring a kid lookout for them who kept making 007 references, having seen Goldfinger27 times.
Mean Character, Nice Actor: German actor Gert Frobe as Goldfinger. He was a member of the Nazi Party, and the film was consequently banned in Israel for many years until it was revealed that he secretly helped Jews flee the country.
Harold Sakata as Oddjob too; Sakata had a reputation as a gentle giant off screen.
The Other Darrin: The start of a long chain of Other Darrins for Felix Leiter, as Cec Linder takes over the role from Jack Lord (who wanted too much money to return to the role).
