Val Kilmer easily turned in one of the best roles in his career as Doc Holliday in Tombstone, and the fact he didn't receive an Oscar nomination is deeply frustrating. Released in 1993, Tombstone tells the story of Wyatt Earp and his brothers' infamous gunfight at the O.K. Corral. One of two movies released around the same time about Wyatt Earp's life, Tombstone remains the most popular of the pair, but critics mostly dismissed it that year, and it lived life as a mainstream blockbuster that became a cult classic.
