In common with alot of the poster here, many / most / all of us not only share an interest in John Wayne movies, but perhaps an interest in the culture and history of the American West.
I just finished rereading a great book about the life of Wyatt Earp and it reminded me about all of the movies that have been made about this legendary character and the famous fight that took place in Tombstone, Arizona on October 26, 1881 - Gunfight at the OK Corral / Hour of The Gun / Wyatt Earp / Tombstone and My Darling Clementine quickly come to mind.
Of these films, my favorite probably has to be Kevin Costner's Wyatt Earp.
Yes - it was essentially panned by the critics for being too long, but I enjoyed it because I thought it provided the most realistic depiction of this very complex man. As well, it gave us a glimpse into the life of Wyatt Earp from a young boy right up to the infamous fight at the OK Corral. And you have to give credit to Dennis Quaid for dropping alot of weight to capture the "tuberculosis" ridden look of Doc Holliday.
Tombstone was also very good, but I thought it was more of an entertaining film - with an incredible Doc Holliday portrayed by Val Kilmer - as opposed to Costner's more ambitious epic film. Kurt Russell's moustache, though, wins hands down of all the Wyatt Earp character's moustaches.
My Darling Clementine is a beautiful John Ford film with Monument Valley again as the backdrop and Henry Fonda is a pillar of integrity and character as Wyatt Earp. However, I thought Victor Mature was a weak and not terribly believable Doc Holliday
The Hour of The Gun stars James Garner as a very passable Wyatt Earp and Jason Robards as Doc and is another one of those very entertaining fims that I can watch a hundred times and never get bored.
Finally, Gunfight at the OK Corral pairs Burt Lancaster as Wyatt Earp and Kirk Douglas as Doc Holliday. An entertaining film, but not one of my favorites,
