Plot hole: The factory in Norway has to be destroyed - at huge cost - as it is producing fuel for the V2 rocket. That fuel was ethanol - ordinary industrial alcohol. There is no reason at all to have a specialised factory hundreds of kilometers away producing such a simple chemical. The Germans could have manufactured it in virtually unlimited quantity in an ordinary brewery - and there were plenty of those in Germany.
Plot hole: When the boys go to get Ringo out of the police station, the other 3 are in front of the police officers and Ringo is way behind strolling along with his camera. When they get trapped in the courtyard they are all together. How did Ringo manage to pass all the policemen with out getting arrested, whilst going slower than everyone else?
Plot hole: Goldfinger wasn't planning on Mr. Solo breaking away from the rest of the gangsters before Goldfinger could have them all killed by the nerve gas so it makes no sense that there would already be a truck from the stud farm waiting for Oddjob to drive back with the remains of the crushed car. It also begs the question if Oddjob had to drive the truck back to the farm where is the guy that drove it to the junkyard in the first place?
Plot hole: The man with no name kills five Rojo bandits outside the city, in the so-called small house. His gunfire is heard in the town, where other Rojos respond by riding to the place of incident. In the film time, it is daytime. Shortly afterwards, the man with no name starts a fire. It is now night in the film. A fire alarm is sounded. Many scramble to extinguish it. Rojos then toss the entire town, looking for the man. Soon after that, Rojos blow up the external fence of the Baxter residence. So much ruckus in town until this point, but not a single Baxter has reacted. They still won't react until one minute later, when Rojos have set fire to their residence. 34 Baxters die on screen. Seriously, where were all these Baxters all this time? In a soundproof chamber of some sort? In coma? (01:02:10)
Plot hole: In the beginning, Charlotte insists to Velma that cousin Miriam is coming, but Velma says "She's never answered any of your letters." And Drew says she's not coming. But when Miriam does come, only seconds later, Velma and Drew now act like they were expecting her. Velma says "You nearly beat your telegram. We weren't expecting you till tomorrow." It's like the film has been badly edited, with Miriam's announcement of her arrival ending up on the cutting room floor.
Plot hole: Turgidson's 'secretary' listens to the incoming telephone messages for only a second or two, and relays a much longer message than she could have heard during that time.
