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)
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.
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.
