Inevitable comparisons will be made between this epic, and the more action-oriented TOMBSTONE. Both films came out within several months of each other, and the general impression I get is that Tombstone seems to be the favored film. That being said, I have to say that I like one as much as the other, although they are two very different films covering familiar ground. I've always been fascinated with the stories, and I think the only way you could really tell what "historically happened" would be to travel back in a time machine and take a front row seat! I appreciate that this film takes a look at Wyatts checkered past, leading up to the events at the OK corral. His character doesn't seem to be "whitewashed", and the man is definitely not perfect, but you can appreciate him just the same.
In the past, I thoroughly enjoyed director John Sturges' decades-apart films of the events, GUNFIGHT AT THE O.K. CORRAL(1957) and HOUR OF THE GUN (1967). I despise director John Ford's rediculous MY DARLING CLEMENTIME ( Tombstone,Az. set in Monument Valley? Pretty cute considering they're 505 miles apart, just for starters.) Frank Perry's DOC (1971) is a depressing mess.
Anyway, I highly recommend WYATT EARP as both an epic of the American West, and yet another fascinating version of the events preceding, and following probably the most famous shootout in American history.
I also recommend Blake Edwards' SUNSET, a fun imaginative story set in Hollywood in the 1920's, where Wyatt Earp (James Garner) arrives to be a technical advisor on a western starring Tom Mix.(Bruce Willis).
