Other mistake: Near the end, as Van Helsing parts the wooden fence and enters St Botulph's churchyard, the camera tilts up and catches two builders on top of a construction sight watching the filming.
Factual error: When Sally and Bryan are in the street, we can see, at their back, election posters. These posters appeared in 1932, one year after the movie is supposed to take place.
Continuity mistake: Watch the hotplate in the café scene before Mike puts the sausages in the oven. You can see that on the left hand side of the hotplate there is a large portion of fried egg white, but when we see Mike putting the sausages in the oven, the egg white has changed into a fried egg.
Continuity mistake: Fiona Fullerton's eyebrows change from full to plucked and back again all through the film.
Visible crew/equipment: When Robert and Arvid are in the desert and Robert falls into the pit, you can see the shadow of director Jan Troell holding the camera.
Continuity mistake: As Allen is preparing for his blind date, he knocks almost everything off the second shelf of the medicine cabinet, while trying to control the hair dryer. When the camera changes position, however, it's all back on the shelf. (00:21:30)
Continuity mistake: When Tintin and the two kids are escaping from the submarine lair, the water level keeps changing. It's supposed to be more and more high, but it's lower in some shots.
Other mistake: In the shot where the men are playing a game of baseball, if you look carefully in the background you will see that cars are driving down the highway. Considering that this movie was supposed to take place in the 1800's...
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.
Visible crew/equipment: When Spencer and Hill fly the second air plane, the studio headlights are mirrored in Hill's sunglasses. (00:20:35)
Factual error: When Craig is being tortured in "New York," a spy operative threatens to plug in the electric shock machine in a European socket/outlet, rather than an American-type socket.
Factual error: The colt .45 that Telly Savalas uses didn't come into use until 1911 (the film's set in 1909).
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: When KC Carr visits her mother, daughter, and son she's shown leaving in a taxi. Later she's shown driving her own car. That car seems to vanish when she joins another derby team who travels by bus. Surely the other derby teams she was on had buses.
Continuity mistake: Karen's barefoot on the dock and walking to the house, but once in she's suddenly wearing sandals.
Revealing mistake: When Itto is bathing, near the beginning of the film, he hears the clanking sound and then there is a close-up shot of his face. The start of his wig, the hairline, is visible. (00:08:48)
Visible crew/equipment: After defeating Gunbei in a duel, Itto enters a temple to pray to Buddha. As Itto walks to the altar the camera passes by a number of pillars and statues and the shadow of the camera is cast on them a couple of times. (00:34:24)
Continuity mistake: The mafioso with the rainbow scarf hands his boss a drink, extending his arm. The next shot begins with his arm bent, and the third mafioso acting as barista is also in a position inconsistent with the previous shot. (00:15:00)
