Continuity mistake: When they pick up Warren on the stagecoach, the second shot from inside has the wrong direction of landscape outside, so it seems that Warren changed from the front to the back row.
Revealing mistake: In one of Pickett's charge scene the bayonets are obviously rubber.
Continuity mistake: At the end of the film when all the women are dressed up after making clothes out of tablecloths, you can see the Italian woman riding in the front of the wagon. The shot changes and she's riding on the side looking at all the men and smiling. The shot changes again and she's back to the front.
Revealing mistake: In the scene where Captain Love and Antonio Banderas (as Zorro) meet in the hallway of the hacienda, two guards rush down the hallway and drop their rifles and swords. Zorro asks them to bend over and then proceed to kick/nudge them out the window. If you watch carefully, you'll notice that the guard on the right (furthest from Zorro) reacts to the kick too early. (01:33:30)
Factual error: Near the end of the film Butch is complaining about the living conditions they have to endure - jungles, swamps, snakes, night work - and Sundance sarcastically retorts "Bitch, bitch, bitch!" In 1908 the term meant just what it literally means: "Female dog." It did not adopt its current meaning of "complain" until much later. At the time the film is set - outside the context of "female dog" - it was considered to be a serious obscenity, and it would not have been used to describe something as ordinary as someone moaning about his living conditions.
Continuity mistake: When the crook kicks the door on a building in the fake town it falls over, but the same building falls over again when the dynamite goes off. (01:21:25)
Revealing mistake: In the scene where Cobb's mean attack Emmitt, Mal shoots one of the men in the hand. The shot pauses long enough to show that hand is quite a cheap, plastic-looking fake prop hand.
Continuity mistake: When Edwards is teaching Hunt the alphabet, whenever he turns it around or you see it from another angle, the upper and lower case changes.
Visible crew/equipment: When the guitarist almost gets hit by a bus, you see a shot from inside the bus about what happens outside. If you watch carefully you can see Robert Rodriguez in the rear view mirror holding the camera with a towel on his head. (00:27:00)
Continuity mistake: In one scene, Steve Martin is shot in the arm and bleeds, but when the trio return after the riot the wound has disappeared.
Continuity mistake: In the final scene at the sheriff's office, Mitchum has his feet up on the table top, and the boot soles are clean. But after Wayne walks out, there is suddenly a spot on a boot sole. (This is visible in the video)
Character mistake: When Wes is drinking the mezcal with the worm in it, he makes a toast to "la vida luna" and tells Sissy it's Spanish for "the crazy life". This is untrue, the correct Spanish translation for "the crazy life" is "la vida loca". "La vida luna" literally translates as "the life moon" or better yet "the moon life", but a more accurate translation is "the night life."
Continuity mistake: In the final shoot-out scene where Clint Eastwood kills 5 men in rapid succession, Clint crouches and exchanges gunfire with two deputies who are standing side-by-side. A blood stain suddenly appears on the abdomen of the younger deputy on the left, but there is no bullet hole, it does not coincide with any gunshot sound effect, and the deputy does not react to the wound. A moment later, as Clint continues firing, both deputies topple over backwards.
Continuity mistake: In the scene where the Spaniard is beating up all the guys that Maverick paid off he ties one guy's neck to a post with his whip. As the shot changes you see the whip go only around his neck, but in the last shot of the scene it's around neck and post again. (00:36:00)
Factual error: The aged brave, singing his death chant, has fillings.
Revealing mistake: Although the film is set during the aftermath of the Mexican War (1848-50), the mountain vistas display some lovely radio towers and fire ranger stations.
Continuity mistake: In one of the final scenes where Tom Selleck has a gunfight with Alan Rickman, the time of day during the few minutes (in movie time) the scene takes place varies from noon (full sunlight) to dusk. Just prior to the gunfight, when Selleck is getting ready to draw on Rickman and his two henchmen, there are almost no shadows and there is bright sunlight indicating it is in the middle of the day. Just after the gunfight there are now long shadows on the characters and moments later the camera pans across the hills and the sun is setting.
Suggested correction: Shadows exist before and after try to watch it again.
Revealing mistake: In the extended version of the film during the buffalo hunt, there is a shot of a buffalo making a turn and in the distant horizon, you can briefly see a modern radio tower on top of a hill.
Visible crew/equipment: In the scene where Laura is being attacked in the desert, the camera swings wildly. During this swing, the entire crew becomes visable for a split second. You can see Clint Eastwood (who also starred in the film) sitting in his director's chair, wearing a white t-shirt and watching the filming closely. (01:19:54)
Other mistake: In the Todd-OA version, just before the song "Oklahoma." Gordon MacCrae puts his hand on the porch post and the post moves off the rail. He then pulls it back.
