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: During the food fight in the cafe, the cream on the cafe owner's face keeps disappearing and re-appearing between shots.
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).
Revealing mistake: When O-Yuki is having a flashback to the duel she had with her trainer, at one point he "magically" sets his sword on fire. However, if you watch the scene carefully you can see a cord that runs from the sword into his robes, probably some kind of fuel line. You can see it twice: once in a wide shot showing the trainer and O-Yuki when he laughs and slowly raises the sword and a second time when he blocks O-Yuki's attack and punches her in the stomach. (00:45:58)
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 Mr. Kumagoro visits the Uncle at the hospital, he drops a package on him; the niece looks at him startled, her arms crossed in a different position between shots.
Other mistake: The movie opens with a quote from Lewis Carroll, mistakenly credited as Carrol with just one L.
Revealing mistake: When Itto puts the cover on the baby carriage it's obvious that the sudden downpour of rain is just a sprinkler placed in front of the camera. Pay attention to the cover, Itto's clothing and the puddle behind the carriage, they remain completely dry/untouched. (00:11:00)
Revealing mistake: The protagonist jumps from a bridge and boards the train to try to save the Professor. When he is walking on the top of the carriages, look at the treetops in the background; the train is stationary. (00:12:00)
