Continuity mistake: In the penultimate scene when Susan has just gotten off the train and is running to Ned Trent, you see her fall over flat on her face and then sit up. Cut to the close up where Ned has also fallen over, Susan is flat on her face again. (01:36:00)
Factual error: The film has the Earps arriving in Tombstone whilst on a cattle drive, however, the Earps were never cowboys. They were lawmen and gamblers. It also depicts Virgil being killed, who in fact lived until October 1905.
