Winchester '73 (1950)

In director Anthony Mann's serious 'psychological' western (the first of eight films with James Stewart, including five westerns):

• the many close-ups of the revered, prized, and rare Winchester '73 lever-action rifle, coveted by many of the characters, and leaving a trail of deaths
• the exciting, evenly-matched, July 4th, 1876 (Centennial) marksmanship shooting contest in Dodge City, Kansas presided over by Marshal Wyatt Earp (Will Geer)
• the character of slightly mad, obsessed and vengeful frontiersman Lin McAdam (James Stewart) in a relentless pursuit of villainous 'black sheep' outlaw 'Dutch' Henry Brown (Stephen McNally) who stole and possessed McAdam's prized, one-of-a-kind and rare Winchester '73 rifle that he had won in the film's long opening sequence
• the character of psychotic, sneering killer dandy 'Waco' Johnny Dean (Dan Duryea), who acted lasciviously toward saloon girl-singer Lola Manners (Shelley Winters) and provoked her cowardly fiancee Steve (Charles Drake) into a deadly gunfight
• the scene in Jenkins Bar (across the street from a Wells Fargo Bank in the process of being robbed in Tascosa, Texas) when McAdam grabbed Waco's left arm, twisted it behind his back and disarmed him, and pounded his face into the bar, before defending himself and shooting 'Waco' to death in the dusty street
• the film's climactic chase and deadly shoot-out near Tascosa, Texas between McAdam and 'Dutch' on a hilly rock cliffside - and the revelation that they were estranged brothers (and 'Dutch' - actually Matthew McAdam - had murdered their father by shooting him in the back in cold-blood)
