Overview
Colt .45 is a 1950 American Western film directed by Edwin L. Marin and starring Randolph Scott, Ruth Roman, and Zachary Scott. Reissued under the title Thundercloud, the film served as the loose basis for the television series Colt .45 starring Wayde Preston, which premiered seven years later. Written by Thomas W. Blackburn, author of the lyrics to The Ballad of Davy Crockett, the film is about a gun salesman and gunfighter who tracks down a killer who stole two new Colt .45 repeating pistols leaving a trail of dead bodies behind him. The revolvers used in the movie were actually first model .44 Caliber Colt revolving belt pistols made in 1849 and reaching final form by 1850. Scott correctly demonstrated how to load them so the producers of the film were most likely aware of the anachronism in the title.
Plot
In the town of Red Rock, gun salesman Steve Farrell demonstrates the new Colt .45 repeating pistols to the sheriff. The demonstration is interrupted when men arrive to transfer one of the prisoners to another jail. As he's being led away, prisoner Jason Brett grabs the pistols, shoots the sheriff, and escapes. Convinced that Farrell was involved in the escape, the townspeople arrest the innocent gun salesman. Brett initiates a campaign of robberies and cold-blooded murder, with regular guns being no match for his Colt .45 pistols.
Farrell is released from jail due to a lack of evidence. He tracks Brett into Texas and comes across a band of Indians whom Brett has killed to provide cover for a stagecoach robbery. The only survivor of the attack, Walking Bear, tells Steve about Brett's plan. Farrell jumps onto the stage to fight off Brett's gang with his own set of Colt .45s. The only passenger on the stage, Beth Donovan, tries to prevent him from fighting off the robbers.
After Brett's gang retreats, Farrell stops the stage and notices a white scarf hanging outside the stagecoach window. Believing it to be a signal to the robbers, Farrell suspects that Beth is part of the gang; she escapes on horseback while Farrell is helping the wounded stagecoach driver. Farrell does not know that Beth is the wife of Paul Donovan, one of Brett's associates. Beth returns to her home, which is being used by Brett as a hideout. Although she believes that her husband has been forced to work with Brett, he is actually plotting with the killer to take over the nearby town of Bonanza Creek.
