El Dorado (1967) - 9 mistakes

Continuity: As the sheriff returns from getting 'his evening bottle', the camera view from the rear shows his hat brim turned up. But when the view changes to the front, the brim is down. this change happens twice.

Factual error: Josephine, shooting from above, hits Thornton somewhere around his hips, in the area of his lower thoracic or upper lumbar region. The bullet is never removed, and Thornton has trouble later with his right hand going numb. A bullet pressing on the spinal cord in the area where he got shot would impact his legs and feet, not his arms and hands.

Factual error: The town of El Dorado is located in Texas, as evidenced by the Texas county map on the wall in the County Sheriff's office. However, while on their journey to the town, Thornton and Mississippi shoot at Saugaro Cact, which is only found in the Sonoran Desert in what was then Arizona Territory.

Revealing: During Cole and Mississippi's night patrol, a bunch of horsemen start making a fuss in the street. When Mississippi dives under their horses, there is an interruption between when he dives, and when he (supposedly) lies in the horses' path. Evidently, this scene was made by joining two cuts.

Factual error: The movie takes place in the late 1860's or early 1870's all through the movie Josephine Mcdonald is shown A.) wearing pants and B.) riding her horse astraddle(one leg on each side of the horse)this was such a huge breach of decorum for the time that any woman who did so would be labeled a whore (or worse)and no self respecting father would EVER allow his daughter to do so in fact this behavior was so nonexistent that Martha Jane Canary (Calamity Jane) who was prostitute was known and disrespected all over the west for dressing as a man and even she rode sidesaddle.

Continuity: 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)

Continuity: When Cole throws the bucket of water on J.P. in the jail, J.P.'s shirt is soaked but his left arm is dry. His left arm changes back and forth from dry to wet.

Continuity: In the cafe after Mississippi kills someone, Cole shoots the gun out of the hand of another gunslinger. The gun goes flying behind him past the piece of furniture along the wall. Later the gunslinger goes to pick up the gun which has appeared at his feet.

Continuity: During the gun battle at the church, the bad guys are up in the bell tower shooting down on John Wayne's good guys. This is taking place in the middle of the night, but when the camera pans up towards a bad guy being shot in the tower, the sky behind him is obviously bright blue.
