Best thriller movie mistakes of 1972

Revealing mistake: When Sonny is punching Carlo under the spraying fire hydrant, he misses an audible punch by at least six inches. (01:43:30)

Continuity mistake: When Lawrence Olivier and Michael Caine are playing snooker, Olivier pots the black. There is then a wide shot, with the black visible again on its spot. The next shot is a close up of Olivier picking the black ball from the pocket and replacing it on the table.

Visible crew/equipment: When Rev. Scott swims up the first stairwell, after pushing aside the dead crew member, as his head comes up the shaft, you can see, very quickly, the flippers of a crewmember swimming out of the shot behind him. (01:22:55)

Visible crew/equipment: Near the end of the chainsaw sequence, a crewmember's hand is visible on Krug's back.

Revealing mistake: When the mountain man is grinning at Jon Voight tied to the tree, you can see that his "missing" front tooth is actually painted black.

Continuity mistake: Watch the bar scene about ten minutes from the start of the film. The barmaid is holding 2 pints, but note how the froth disappears when the shot changes as they are placed on the bar.

Continuity mistake: After Bruce Lee kills Chuck Norris, he walks back and picks up Chucks Gi and Obi (karate shirt and karate belt). The belt is hanging and dragging on the floor but as Bruce walks from behind a column, the Obi appears to be folded properly.

Continuity mistake: At the end of the film when Oliver Reed is in the Range Rover and ramming the Hillman Avenger, watch the number plate of the Avenger. It switches repeatedly between a 'K' suffix and a 'J'.

Audio problem: When Bruce Lee finishes fighting with the Japanese school using a nunchaku and is going to fight with the fat man, he folds the weapon and tosses it to the floor on his left. It lands without making a sound.

Continuity mistake: Several characters say that the train leaves from Shanghai. But the caption at the beginning says that the starting location is Peking (which is in fact where the real Trans-Siberian Express did depart from).

Continuity mistake: When Abel rams the sheriff's car, he is driving a 1966 Chevrolet. He leaves and ends up at the veterinary clinic, where the doctor injects him with a poison. During the following chase, Abel's car becomes a 1967 Chevrolet, then reverts back to the '66 Chevy.

Continuity mistake: While Prince Mamuwalde struggles with Count Dracula's goons, some candles are knocked off a candelabra, but the next shot shows the candelabra with the full complement of candles it had before the fight.
