Corrected entry: When Cleavon little says good morning to the elderly woman, she responds with a nasty "Up yours n*gger" comment. Later on, the woman apologizes for the incident and gives him an apple pie. But the woman who apologizes is not the same actress who insulted him earlier even though it's meant to be the same person.
Corrected entry: In the Governor's office, the US flag is a modern flag with all 50 stars. There wouldn't have been nearly as many during the time the film took place.
Corrected entry: When the gang rides into fake Rock Ridge, the buildings constructed by the townsfolk are two-dimensional. After the explosions begin and the fighting between the two groups begins, the structures are suddenly real. At the end of the picture the street in both towns have sagebrush and desert plants. Earlier in the movie, the town streets are clear.
Corrected entry: The "welcome sheriff" banner rolls up after the realization of the new sheriff's race. Though meant as a sight gag, you can tell the man in the tan suit closest right behind the woman in the blue shawl pulled the banner to make it roll up, though he tried to do it in a sneaky way.
Corrected entry: In Jim's first scene, after he is straightened out from being upside-down, hanging off the top bunk, he reaches under the pillow for a bottle. He then finishes the remains of the bottle. The level of the liquid changes. It goes from being just above the bottom of the label to being enough for 4-5 big swallows. (00:33:15)
Corrected entry: A man and his horse are being hanged. When Hedley Lamarr looks out of his office window for the second time, he tells Boris he has a special, and Boris replies: I couldn't possibly fit him in until Monday, sir. I'm booked solid. The scene shows the man sitting on his horse, on the scaffold - and you can see power lines in the background. Movie is set in 1874.
Corrected entry: In the scene at the end of the film when the entire cast runs through the main gates of the studio and out into the street, Hedley Lamarr hails a taxi. As he gets in, a couple of people who are supposed to fight and chase each other are seen on the other side of the street just standing there, seemingly waiting for someone to yell "cut."
Corrected entry: During Lily's "I'm Tired" number, watch when she reaches to rest her hand on the shelf behind her. She obviously misses the first time.
Corrected entry: On the DVD in the shot where Mongo punches out the horse, the microphone is visible in the bottom right corner of the screen.
