The Deadly Trackers (1973)

Synopsis
Based on filmmaker Samuel Fuller's short-story "Riata," this extremely bloody, excessively violent and long-running western centers on a vengeful sheriff's search for the murderous bank robbers who slaughtered his family. Originally Fuller was the director for the film, but severe artistic differences between himself and the film's star Richard Harris forced the studio execs to put in a new director, Barry Shear. They also dumped the million dollars worth of footage Fuller shot and started from scratch. ~ Sandra Brennan, All Movie Guide
