a steam train through the town saloon. A gunfight ensues between Kidd and Harlan's men. Kidd triumphs over the other men and manages to kill Harlan in the courthouse by hiding in the judge's chair. Chama then surrenders to Mitchell. Kidd punches the sheriff (because the sheriff had punched him during the poaching arrest), collects his things and leaves town with Helen. Cast Production Eastwood was given the script by Jennings Lang, written by novelist Elmore Leonard. Originally called The Sinola Courthouse Raid, it was about a character inspired by Reies Tijerina, an ardent supporter of Robert F. Kennedy, known for storming a courthouse in Tierra Amarilla, New Mexico in an incident in June 1967, taking hostages and demanding that the Hispanic people have their ancestral lands returned to them. Leonard depicted Tijerina in his story, a man he named Luis Chama, as an egomaniac, a role which went to John Saxon. Robert Duvall was cast as Frank Harlan, a ruthless landowner who hires Eastwood's character, a former frontier guide named Joe Kidd, to track down the culprits and scare them away.

Outdoor sequences to the film were shot near Bishop, California, southeast of Yosemite National Park. The actors were initially uncertain about the strength of the three main characters in the film and how the hero Joe Kidd would come across.

During production, the script for the finale was altered when producer Robert Daley jokingly said that a train should crash through the barroom in the climax, and he was taken seriously by cast and crew, who
