Other mistake: After Sonny is shot on the causeway, there are a very large number of bullet exit holes visible on the sides of the tollbooths, which could only have been made if the gunmen shot through the walls (not the windows) of the buildings from the inside. This is common in movies. In real life, bullet entry holes in wood appear as small black dots, not the more dramatic-looking splintered gashes made on the other side of the wood as the bullet exits.

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.
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...
Other mistake: In the scene where Kidd is in the watchtower getting ready to smash the guy in the head with the water jug. When he lowers it, it looks to be about 3/4 full, but when it smashes the guy in the head, about a cup of water comes out.
Other mistake: During the ‘rescue' mission to save the trapped wagon train, none of the riders are carrying packs of food or any supplies. One man is carrying a military unit banner on a pole. Unrealistic for this type of activity.
Other mistake: When the gunman is sitting in the boss' office, the morning after failing to bring Bruce to him, he is shown with a black eye, band aid on his forehead, and the other eye swollen - despite only receiving strikes to the midsection by Bruce the night before.
Other mistake: When the survivors are in the funnel, there seems to be an explosion that comes from under them. Since the deck they were on was flooding, all the decks below would have been flooded. Whatever explosion that would've occurred in the funnel would have come from above, where whatever machinery was left would've caused it.
Other mistake: When the wrapped body parts are going for the mistress (the one telling the story), you can see the right arm dragging itself across the floor. However, the arm that grabs her face from above is also a right hand. How did the murdered wife have two right arms?
Other mistake: The film is set in 1931. One of the characters uses the phrase "plenty of nutting." This phrase comes from the song composed three years later in 1934 for the musical Porgy and Bess.
Other mistake: We know that, after Cornelius and Zira were executed at the end of the previous movie, "Escape from the Planet of the Apes," baby Caesar was only an infant who was just starting to say "Mama." In "Conquest," we know that 20-year-old Caesar was raised (and secretly educated) by Armando, the circus owner. But, after 20 years of being raised and secretly educated by Armando (who has a thick Mexican accent), Caesar has a distinct British accent.
Other mistake: When Lorry driver goes around the back to put the door up, you can see the type of lock, but when they zoom in, it's like a peg you slot in, then when they zoom out it's the other type of lock. (01:19:16)
Other mistake: When Stan is towing Arthur's motorbike and sidecar behind the bus the tow rope was attached to the handle bars, when the handle bars come off, the bike naturally breaks away from the bus and rolls off on its own, but it is going back the way it was when it was being towed. The bike couldn't have turned 180 degrees with no handle bars to steer it.
Other mistake: Just one second after Sadie asks Bert if he is all right after falling from the balcony, Bert opens the door, covered in cement.
Other mistake: It makes no sense that the pimp would die from having the tip of his tongue bitten off. (00:23:35)
Other mistake: The opening credits misspell the name of production supervisor Peter Sczygiol ('Sceygiol') and firearms technician Gino Vagniluca ('Vigniluca').
Other mistake: During the opening sequence there is a shot of a muddy river where we are shown the credits for Director of Photography, Camera, Sound, Film Editor etc. When "Camera" is credited there is a number 2 next to it, that is the order in which the credit appears, but none of the other credits are numbered. (00:06:20)
Suggested correction: That's not a mistake. Fransisco Joán and Orlando Macchiavello were second cinematographers (2. Kamera in the original German film credits).
Other mistake: The movie opens with a quote from Lewis Carroll, mistakenly credited as Carrol with just one L.
