More Westerns are on tap, all day and night tonight, as TCM continues its celebration of Western month on Tuesdays and Wednesdays. Tonight, in prime time, the better ones arrives, starting at 8 ET with 1967’s Hour of the Gun, one of many Westerns telling the story of Doc Holliday and Wyatt Earp. Jason Robards and James Garner star in those respective roles, and John Sturges directs.
