Continuity: The bomb is disarmed with 007 seconds left on the conveniently placed timer with big white numbers. Then, Bond says "Three more ticks and Mr. Goldfinger would've hit the jackpot." What? Well, originally, the timer would've stopped at 003, and the line would make sense, but later the powers that be decided to stop it at 007 instead for a good old Bond joke, and apparently never forgot to delete that line in editing. [The 3 clicks mistake is an interesting one as there are still in existence cuts of the film with the original 003 on the nuclear device timer.  One contributor saw the 003 version in 1970 and was puzzled when the 007 version turned up on TV years later.]

Continuity: You can see when the black Lincoln that Oddjob drives to the junkyard is lifted to be crushed, it has no engine.

Revealing: When Bond is on Goldfinger's plane - if you watch closely when it shows the external view of the plane in the sky you can see the plane is a model with two wires holding it up.

Visible crew/equipment: During the scene at the golf club, when the Rolls Royce begins to move off, the reflection from one of the film set lights can be seen on the rear left hand side of the Rolls Royce: There is no way that this could have been the relection from the sun, because the weather during the scene was on the dull side.

Continuity: When Oddjob drives away from the golf course, Goldfinger is not in the back of the car for some reason, even though they show him in the car earlier.
