Character mistake: In the courtroom scene set in the 1870s, Morgan Earp responds to a defendant with "Nice and easy my ass." While "ass" was used as slang in the 19th century, the dismissive phrase "my ass" as a sarcastic retort isn't documented until much later, making it sound more like 20th-century speech than something cowboys in a frontier courtroom would say, making this an anachronistic turn of phrase.

Factual error: The movie begins at the end of the Civil War, 1865; it then moves ahead 7 years, to 1872 in Wyoming. Several characters are wearing gun belts with cartridges on the belt. The pistols are Colt Peacemakers probably .45 cal. The problem is that the gun and cartridge were not introduced until 1873 and would take several years to become commonplace. (00:18:31)
