Factual error: It is physically impossible for Teehee to hold Bond's Walther in one hand and bend the barrel with his prosthetic hand. The forces involved would pull the gun out of his real hand, which wouldn't be strong enough to keep it in place, no matter how strong the prosthetic hand was.
Visible crew/equipment: When 007 takes the taxi outside the Oh Voodoo Cult Shop, you can see the reflection of the crew on the window of the car.
Continuity mistake: When the guy with the snake is shot, Baron Samedi reappears and you can distinctly see the bloke holding the snake again.
Continuity mistake: In the boat chase, when Bond comes to the shipyard, the goon can't find him. But there would be obvious foam/wake marks and waves after Bond's boat for several minutes.
Audio problem: Before Bond and Solitaire get into Kanaga's den at the end of the movie, we see two guards running. However, there are only footsteps from one person.
Deliberate mistake: In the scene where Bond and Kananga are fighting underwater, Bond shoves the bullet into Kananga's mouth. Then, Kananga rises up and explodes. He explodes like a balloon, with not much blood at all.
Continuity mistake: Watch the way the bloke at the beginning is holding the snake. Every time the camera shows him from behind, he has one hand by its head, yet each time the angle changes to the front, his hand is halfway down the snake's body.
Factual error: In the scene where Kananga's henchman, Adam, is being interrogated by Sheriff Pepper by his car at the riverside, the boat chase arrives and two boats jump clearly overhead, disillusioning Sheriff Pepper and allowing Adam to make a quick getaway. However, as Adam is getting away in his car, screeches can be heard coming from the tyres, but they are on a dry dirt road.
Revealing mistake: When Tee Hee bends the barrel of Bond's Walther PPK, in the close-up, the score marks where the barrel has been pre-cut are visible.
Continuity mistake: After Bond has finished ripping the wings off the Cessna and parks up, he speaks to the old female pilot, and in doing so, the camera shows that the wings behind her head are still intact, when they were already ripped off at this point.
Plot hole: James Bond shouldn't have gotten away at the end of the airport scene, where he steals an aeroplane and pretends to be a flying instructor. He had no wings with which to fly away, and he ended back up right outside the airport. So, the henchmen, who seemed to still be chasing him one shot before he parked, should have been right on him, waiting when he got out of the plane.
Continuity mistake: When Bond and Quarrel goes to shore there are clear shadows and sun reflections, showing it was actually shot at daytime.
Revealing mistake: At the end of the film, when James Bond pushes Tee Hee outside the train, you can see his real arm during one quick shot.
Visible crew/equipment: When Bond and Solitaire are tied to the orange thing you can see a wire on the bullet which makes it fly across the room.
Visible crew/equipment: In New York City, when the taxicab goes up the steps and crashes into the trash cans, the ramp that the car travels on is visible.
Continuity mistake: When Bond is on the small isle in the crocodile pond, one of the crocodiles begins to climb the rock. Cut to Bond and then back at the crocodile who has now turned into an alligator. In the next shot it is once again a crocodile.
Factual error: The henchman with the prosthetic arm bends Bond's gun. It would require something in the range of 1000 pounds of pressure to bend a gun like that. It would be impossible for anyone to generate that much pressure since the arm is driven only by human muscle.
Plot hole: Bond steals the ancient double decker bus, not noted for any kind of speed, and he also doesn't get much of a head start against the police, yet in later shots he's quite a distance ahead of them. Skilled driver or not, it's a bus.
Visible crew/equipment: Four patrol cars are chasing Bond and the villain by the road. Bond and the villain arrive at a dead end and they jump over the road with their boats. The four vehicles collide just after. Look carefully and you will see that the right-seat passenger of the red car and the driver of the blue one wear a yellow protective helmet. (01:32:45)
Factual error: When the camera does a close up shot of Bond in the sky in the Microlight, the fabric is far too loose for it to actually be in the sky. The fabric would be taut as the air flows over it.
Chosen answer: Bond just stored the bullet in his own mouth to hide it. As he puts it in Kananga's mouth he presumably pulls a pin, or forces Kananga to bite it.
