In The War Wagon (1967), two lesser hired guns in the employ of dishonest land baron Pierce deliver a message to expert hired killer Lomax, played by Kirk Douglas. They tell him that Pierce is upping the bounty on wronged hero Taw Jackson, played by John Wayne. Lomax was brought into town specifically to kill Taw Jackson for Pierce. But Lomax and Jackson have apparently gotten past the need to kill each other on sight.
