* DawsonCasting: Dana Delany as Josephine Marcus. Delany was 36 when she played the role of a 20-year-old actress working the towns of the Wild West.
* DuelingMovies: Dueled with ''WyattEarp'' (1994) with Creator/KevinCostner. Where Costner's film focused on a more thorough (over 3 hours!) and historically-accurate telling of Wyatt's life, ''Tombstone'' focuses mostly on the events in Tombstone and [[RoaringRampageOfRevenge the immediate aftermath]]. ''Tombstone'' was also the clear victor at the box office, more than doubling its modest $25 million budget with a domestic take of $56m (the equivalent of just over $80 million today). ''Wyatt Earp'', on the other hand, had more than double the budget ($65m) of ''Tombstone'' but wound up with half the gross, with a meager $26m domestic total, one of a string of flops in the mid-90s for Kevin Costner.
* DyeingForYourArt: ValKilmer got the emaciated and sickly look of Doc Holliday by eating almost nothing but onions and tomatoes for weeks before filming started.
* HeyItsThatGuy: Let's see in the Corner of the Earps you have [[Film/EscapeFromNewYork Snake Plissken]], [[Film/RoadHouse Wade Garret]], [[Film/{{Aliens}} Hudson]], [[Series/TheWalkingDead Merle Dixon]], And [[Film/BatmanForever Batman]], With Mayor [[Film/TheRocketeer Howard Hughes]] supporting them while they face off against a gang of cowboys lead by [[Film/RedDawn1984 Lieutenant Col. Tanner]] and [[Film/TheTerminator Kyle Reese]] and including [[Film/SpiderMan3 the Sandman]] and [[Film/{{Avatar}} Col. Miles Quaritch]].
* TroubledProduction: From the start, Kevin Costner was placing pressure on studios not to finance the picture (''Tombstone'' and ''Film/WyattEarp'' were two halves of the same project that more or less split off due to CreativeDifferences between Costner and writer Kevin Jarre), with Buena Vista (Disney) stepping up at the last minute. Disney refused to have anything to do with the original choice for Holliday, Willem Dafoe, due to the controversy still surrounding ''TheLastTemptationOfChrist''. Jarre was originally set to direct, but was fired due to his refusal to cut the screenplay (both Creator/KurtRussell and Val Kilmer have stated the original shooting script was about 30 pages too long). Disney hired George P. Cosmatos to finish the film; Creator/KurtRussell (who had significant pull behind the scenes with both cast and crew) has in recent years made the claim that he directed the picture with Cosmatos as a front (he was the same guy who did ''Rambo: First Blood Part II'', so he was at the very least agreeable to actor input), and at least some of Jarre's directoral work is still in the film. As a cherry on top of all of this, the actor playing Old Man Clanton, Robert Mitchum, was injured in a horse-riding accident, which led to the part being cut entirely (although Mitchum was able to do the beginning and ending narrations).
