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.
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 Kananga and Bond are fighting a cable protrudes under Kananga's jacket, it even lifts up his clothes. Seemingly the mic cable. (01:54:27)
Continuity mistake: The scene where Bond leaves the voodoo shop to tail the car. He hails a cab. As the cab draws up, we briefly see the cabbie in the front, who does not have long sideburns/mutton chops. However, shortly afterwards when the cabbie starts talking to Bond, and we see him more, it is a different actor (Arnold Williams), who has noticeably long sideburns. The driver has changed.
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.
