Factual error: After the O.K. Corral shootout, the Cowboys get revenge on the Earps by shooting Virgil and Morgan Earp on the same night. In reality, though, Virgil was shot in December of 1881, while Morgan was shot in March of 1882, a span of a few months.

Continuity: When Curly Bell shoots the marshal he is seen with his gun in his right hand. Wyatt is then seen hitting him over the head and as he falls to the ground the gun is nowhere to be seen.

Continuity: In the scene where Ringo (Michael Beihn) and Doc Holliday (Val Kilmer) are insulting each other at the casino. We see a shot of Wyatt's right hand under the card table reaching for a gun conveniently hidden ready to shoot Ringo in the balls. In the next shot we see Wyatt still has his right hand as well as his left on the table holding cards.

Continuity: After Wyatt obtains his 25% stake from the Oriental, he is seen walking over to his brothers and putting his cigar in his mouth. The camera angle changes and he is now seen putting his arms around his brothers shoulder's and the cigar is now in his left hand. (Time)

Deliberate "mistake": According to all accounts, the Earps arrived in Tombstone in 1880, had the famous gunfight in 1881, & left in 1882. In the movie when the Earp's arrive in Tombstone (1881), they ride past Boot Hill Cemetery. Plainly visible is the most famous epitaph ever written: "Her lies Lester Moore, Four slugs from a .44, No Les, No more." The problem is that Lester Moore wasn't killed until 1884. So it's impossible for his tombstone & famous epitaph to be in Boot Hill when the Earps arrived.

Continuity: After Morgan is killed, the Earps leave Tombstone with Wyatt driving a flat wagon carrying Morgan's body and Virgil driving the covered wagon with the women. In the next scene, as they cross the prairie headed for the train station, only the covered wagon appears with a man (most likely Wyatt) riding a black horse in front of it. The other wagon is nowhere to be seen.

Factual error: When they first arrive in Tombstone they go past the Bird Cage Theater, it wasn't built until 1881.

Continuity: Doc has 2 pistols. He alternates rapid firing with standard gunslinging. Although he never reloads, he has one shell for the last guy.

Continuity: In the scene where the Earps are playing pool and the mayor is trying to get them involved, Virgil is wearing a sidearm. The following scene when he exits the billiard hall and cowboys are shooting up the street, he reaches to his hip for his gun but it's not there.

Continuity: During the end credits, we are shown the Earps and Holliday walking down the streets of Tombstone. They are all wearing coats in the long shot, but in the first close-up of Virgil his coat is missing. You can see the tip of his shoulder and he is wearing just a white shirt and a vest.

Continuity: In the scene where McMasters is looking through his eyeglass and telling Wyatt how many cowboys there are, there's a shot of Doc coughing with a bloody rag up to his mouth. The camera goes back to Wyatt, and when it goes back to Doc, there is blood dripping out of his mouth and all over his bottom lip and chin. In the very next shot when Doc falls off his horse, about two seconds later, his mouth and chin are completely clean.

Factual error: Just before the famous O.K. Corral shootout, Wyatt retrieves his gun from home.   The gun shown is a 12-inch barrel Peacemaker, but Wyatt received a custom 10-inch version from the people of Dodge City.  The armourer who supplied the guns for the film could not find a 10-inch specimen, and therefore used a 12-inch version.  This fact was stated in an issue of Guns and Ammo magazine.  Incidentally, the man who plays Texas Jack was the technical consultant on the film.
