For a pretty good representation of Western 'dress' of that era, a good, new, Western to rent and watch is "Appaloosa" (Check out the trailer). It stars Ed Harris, Jeremy Irons, Viggo Mortensen & Renée Zellweger. The period costumes are quite authentic as well as the equipment used (saddles, weapons, etc). Viggo as the deputy looks as though he came through a time machine what with his hairstyle, clothing, and weaponry.
As for Tombstone, it was a somewhat accurate portrayal of the Earps while in Tombstone. And it was a fair adaption of the dress and manners of the time. Kurt Russell LOOKED like Wyatt Earp. Sam Elliott did NOT look like Virgil (Wyatt and Virgil were often mistaken for one another). One thing that gave it some reality is the presence of the Earp's families in Tombstone, especially Mattie Blaylock Earp, Wyatt's live-in, who was a hooker Wyatt began living with, probably during his Peoria, IL days. And Josephine Sarah Marcus, his love interest, was the woman he spent the rest of his life with. They did indeed meet in Tombstone, her coming there with a theater group. She actually was the paramour of sheriff John Behan before taking up with Earp.
BTW, Wyatt never was a US Deputy Marshal until Virgil was ambushed after the OK Corral fight. Wyatt solicited and was given Virgil's position after his injury in December 1881, and the killing of brother Morgan in March, 1882. Wyatt wanted the Sheriff's position, but was beaten by Behan in the election.
And there WAS a vendetta ride as displayed.
So whatt did you think of ‘Wyatt Earp’ compared to ‘Tombstone’?
