The Tin Star - a western film directed by Anthony Mann (Destry Rides Again) Starring legendary Henry Fonda (12 Angry Men), and Anthony Perkins (Psycho) in early film. Film received Oscar nomination for Best Writing Story or Screenplay.
Henry Fonda plays Morgan a bounty-hunter who wanders into peculiar town with dead-man wanted by the law for $500 - but it seems he is quite unwelcome in the town, including bank-manager-cum-mayor of the town. Anthony Perkins plays young aspiring Sheriff Ben; who is more than willing to uphold law over lawlessness - he is impressed by actions of Morgan who saves him from dangerous standoff.
The Tin Star was supposedly low-budget film, becoming one of those movies like 'Psycho' to have gained worldwide popularity on the graph over the period of aging. Henry Fonda's use of gun-technique teaching to Perkins, are some of classic methods mentioned in western movies ever (which is a good thing - defines so much about what level of smartness the people of the west carried with gun). It is not stretched with too much of dragging.
