Of all the film versions of the famed 1881 gunfight, this one, starring Burt Lancaster as Wyatt Earp and Kirk Douglas as Doc Holliday, probably has the highest testosterone quotient. Focusing on the friendship between the forthright, responsible sheriff and the risk-taking, consumptive gambler, it suggests that their relationship is based on this opposition of qualities. Wyatt's stormy romance with gambler Laura Benbow (Rhonda Fleming) and Doc's rivalry with Johnny Ringo (John Ireland) over the affections of local madam Kate Fisher (Jo Van Fleet) add to the tension preceding the final showdown. When Wyatt's brothers, Tombstone lawmen, ask for his help in evening the odds against Ike Clanton (Lyle Bettger), his brothers, the McLowerys, and Johnny Ringo, Doc decides to join his friend. After Wyatt gets to town, he quickly puts a crimp in Ike's cattle-rustling activities, which leads the outlaw to set him up for assassination. A mix-up leads to Wyatt's youngest brother, Jimmy (Martin Milner), getting killed in Wyatt's place. Doc tries to talk him out of revenge, but the enraged lawman will have none of it, and the scene is set for the historic final gun battle.
