The events leading up to the gunfight, the shooting of Virgil and Morgan, and Wyatt's vengeful tracking down of the Cowboy killers are all historically correct. Yes, they made up the fight between Ringo and Doc Holliday, but I accept that as dramatic license and there is, after all, somewhat of a mystery as to who really did kill Johnny Ringo.
One interesting aspect of the Earp-Clanton struggle that no movie has ever covered is the political dimension. The Earps were midwestern, Union Republicans while the Clanton cowboys were ex-Confederate Democrats. That set-up bad blood from the beginning and in fact, made their feud a mirror-image of the general fault lines in early territorial politics.
Great point. And didn't that politics also play a role in the (Jesse) James gang?

Many years ago I saw an interesting photo in a western magazine. It was a photo of the Earps and Clantons together in a friendly game of cards.
This was before they had a falling out.
Another excellent movie -- not about Tombstone -- about the James and Younger gangs was "The Long Riders" with the Keach boys, the Carradine boys, and the Quaid boys playing sets of brothers. The final shootout scene in that movie was one of the most graphic and brutal slow-mo shootout scenes I've ever watched. All in all, it was a great movie.
