Continuity: In the film's climax, Ricky Nelson is shooting out a window. A bullet hits on the frame and gouges the wood. In the next camera shot of Ricky the gouge is gone and the following shot, it is back.
Continuity: When Rick Nelson tells Angie Dickinson to throw the plant pot through the window to distract the gunmen who threaten John Wayne he seems to have had a hair cut between scenes as his sideburns are halved by the time he reaches the street and grow again later.
Continuity: About an hour in the sheriff go to the hotel bar and talks to "Feathers". She picks up a bowl and then the camera angle changes and the bowl it back in the corner. Also, the shot glasses they use keep changing positions. They're 4 inches apart then a foot apart then close again.
Other: About 1:15 in, Dude is getting a shave from "Feathers". She does under his nose but when she says she's done and he goes to stand up there is a white strip under his nose. After the towels off it's gone.
Continuity: When Dude is in the bar looking for the man that ran in there, they show a view from the man up in the loft. Look at the pool table in the background. It has balls and cues on it which change positions as that bar scene plays out.
Other: When Burdette rides into town the camera is behind Dude and he has his hands on his belt. The camera angle changes to his front and he suddenly has his left hand on the hitching post.
Revealing: The bullet hole gouge in the window frame near Ricky Nelson and the outward facing splinters at the bullet hole in the door frame near John Wayne indicate exit holes.
Other: About 15 min in the sheriff offers Dude a beer and says "It's cold." Dude, getting off his horse, says "As long as it's beer" but his lips don't match the words.
Continuity: When Dude is in the bar looking for the man that ran in there, there is a mug of beer on the bar. It is right up against the rail. Later, it's in the middle of the bar then against the rail again.
Continuity: After Colorado tells the sheriff what the music is about, the sheriff goes into the jail and sits on the desk. He sits on the brim of his hat on the desk. In the next shot his hat has moved away and in on the inkwell.
Continuity: The brim of John Wayne's battered hat goes through so many changes I stopped counting - in one sequence its bent upward, in the next it is flat, in the next its bent up (even more) again, etc., ad nauseam.
Other: About 45 minutes in Wheeler is walking down the street. The view is from behind a man with a rifle at a window. When he shoots it is obvious the rifle was pointing to the far right of Wheeler.
Continuity: About 30 min in. The sheriff is talking to Wheeler at the bar. They move to a table and the sheriff pulls down the shade. As they talk the camera angle changes and so does the bottom of the shade. Now you see the window sill.
