The Culpepper Cattle Co.

The Culpepper Cattle Co. or Dust, Sweat and Gunpowder Australian title is a 1972 Revisionist Western film produced by Twentieth Century Fox. It was directed by Dick Richards and starred Billy Green Bush as Frank Culpepper and Gary Grimes as Ben Mockridge. This was the first credited film for Jerry Bruckheimer, for which he received an associate producer credit. Its tagline is How many men do you have to kill before you become the great American cowboy? and also The boy from Summer of 42 becomes a man on the cattle drive of 1866, which references a similar coming of age film starting Gary Grimes. The film is typical of the hyperrealism of many early 1970s revisionist westerns. It is particularly noted for its grainy photography and use of sepia toning in some scenes.

Ben quickly discovers that the adults have little interest in youngns, and no interest in showing him the ropes. Culpepper nevertheless assigns Ben tasks the greenhorn handles poorly or simply fails at repeatedly causing serious trouble.After rustlers stampede the herd, Culpepper tracks them to a box canyon. When the rustlers leader Royal Dano demands 50 cents a head for having rounded up and taken care of the cattle, Culpepper will have none of it. He and his hands kill the rustlers, not hesitating to gun down disarmed men, or repeatedly shoot anyone still moving. They lose four of their own in the fight. ........
