I loved the ballad (music by Tiomkin) that appeared throughout the movie. As you say, of all the OK Corral related movies, this one is only outdone by "Tombstone" - the shootout itself is more accurately portrayed in "Tombstone" since history tells us that that incident lasted barely thirty seconds. "Gunfight ..." portrayed the showdown as being much longer in time (as did "My Darling Clementine").
