The Quick and the Dead (1995)

Factual error: In the scene just before Harrod fights Ace Handlin, we see a view of Harrod's feet passing a blood stain in the dirt. This bright red color would be impossible when mixed with the dirt. Also we are led to believe that fights happen on the hour, each hour. The blood would have coagulated and been nothing but a dark spot on the ground. This has obviously been done to emphasize that the ground is bloody.

Factual error: In the first scene of the shoot out competition where Di Caprio is loading his revolver, the ammunition is modern headstamped R-P 44 Colt ammunition. This is modern 1990-2000 ammo.

Factual error: In the bar when the lady buys herself a drink before getting challenged to her first fight, she drops a nickel on the table. It's a Jefferson nickel, not minted until 1913.
