\The classic American Western film might have peaked in popularity with 1993’s Tombstone, thanks to its potent combination of Doc Holliday one-liners, pitch-perfect Old West action, and gloriously mustachioed cast. Each member of Tombstone‘s star-studded cast was integral in bringing the story, which was a glamorized and somewhat exaggerated version of the real historical event known as the Gunfight at the O.K. Corral. At the time of its release, neither the box office nor the critical reception for Tombstone were noteworthy, but its popularity has grown significantly over time thanks to its lasting entertainment value.
