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).
Visible crew/equipment: Near the end of the film, just after one of the soldiers is hit in the chest with a spear and falls overboard, there is a shot of another soldier (who is missing teeth) lying dead on the raft. If you look in the top left corner of the shot you can see the foot of a crew member wearing a modern trainer shoe. (01:22:42)
Revealing mistake: When Anguirus makes his sacrificial charge against Gigan, the hand that is moving the Anguirus costume can be seen holding it.
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.
Continuity mistake: Waldemar Daninsky and Justine are in front of Imre's tomb. She wipes her tears in the wide shot, but in the closer angle, her hands are low, and only then does she bring her right hand to her eyes to wipe those tears.
Other mistake: The movie opens with a quote from Lewis Carroll, mistakenly credited as Carrol with just one L.
Other mistake: It makes no sense that the pimp would die from having the tip of his tongue bitten off. (00:23:35)
