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: 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: There was no way the dining room could have filled up with that much water in that amount of time.
Other mistake: The movie opens with a quote from Lewis Carroll, mistakenly credited as Carrol with just one L.
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: It makes no sense that the pimp would die from having the tip of his tongue bitten off. (00:23:35)
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.

Suggested correction: That's not a mistake. Fransisco Joán and Orlando Macchiavello were second cinematographers (2. Kamera in the original German film credits).
