Continuity mistake: While being chased by the Indians, Charming's shawl is either on or off her shoulders; there is no continuity.
Continuity mistake: When Charming is setting up her bed in the wild, the light is sunny, but from Cactus' aerial POV, it's shadowy. This swaps back and forth.
Revealing mistake: During Cactus Jack's first trap failure while he's under Handsome's wagon, Jack loses his cowboy boots and pants. The camera follows the insane stretching suspenders, and when it cuts to Cactus Jack in his red long johns, the black booties for the stunt are visible at his feet/ankles; then next wide shot, that footgear is gone. Additionally, as Cactus Jack gets pulled toward his pants, it appears that he slides past his pants in the long shot, but is successful in the next close-up. (00:33:00)
Visible crew/equipment: After Cactus Jack shares with Whiskey his dream of buying a nice spread, when Cactus Jack lays trap number four with the rope across the road, he then leaps onto Whiskey, and in the two shots at this angle, we can see the moving shadow of the boom mic on the ground, at the bottom left corner of the screen. (00:40:25)
Other mistake: Handsome and Charming head out of Snakes End (followed by the newlyweds) and begin their long journey. It then cuts to Cactus Jack before he begins the journey, and at the start of this shot as he places Whiskey's bit, we can see the signpost with three wooden arrow signs and the hillside behind him. This is the same location where Cactus Jack lays trap number seven, named "the tunnel in the hillside," on the next day during the journey; noticeable when Handsome and Charming arrive. (00:28:35 - 00:54:45)
Continuity mistake: Cactus Jack's leather cowboy boots have block heels and spurs with rowels and jingle bobs. In quite a few shots throughout the movie, Jack's boots change to no-heel flat soles, and the spurs are missing, though we still hear the distinctive jangling of Cactus Jack's spurs.
Continuity mistake: Despite Cactus' feet being firmly glued to the floor, their position changes noticeably between instant cuts, from being V-shaped to parallel to each other.
Revealing mistake: When Cactus' feet get stuck on the glue, he actually makes a tiny jump, and his heels rise above the wooden planks, giving away the joke.
Continuity mistake: When Cactus is about to be run over by the train, the shadow he casts changes drastically between shots.
Revealing mistake: When Cactus drives the organ and crashes, a long white wire is running off-screen, seemingly to allow for the stunt or the FX.
Revealing mistake: When Cactus is ran over by the train, one can see he is held with several security straps.
