"Showdown With Rance McGrew" is episode 85 of the American television anthology series The Twilight Zone.
Actor Rance McGrew, who stars in a TV series as the fictional heroic marshal of the same name, arrives late to shoot the final scenes of an episode in which his character pursues Jesse James. According to the script, Rance turns away from a seemingly-beaten Jesse, who then tries to shoot him in the back. The actor playing the outlaw says fighting dishonorably is historically inaccurate and asks permission to shout at Rance before firing, but Rance argues that shouting out a warning to a gunman who has already proven himself to be a better fighter makes no sense.
Suddenly, Rance finds himself in a real Old West saloon, where he is confronted by the real Jesse, who says that he, Billy the Kid, and other famous outlaws are not pleased with the way that they are portrayed on Rance's show and consider him a fraud who makes his living off the reputations of true gunslingers before challenging him to a fast draw showdown. Realizing that he stands no chance against a real gunfighter, Rance tries to flee, but Jesse stops him. Amidst the showdown, Rance struggles to get his gun out of his holster before unintentionally flinging it into the air in a panic. His point made, Jesse points his own gun at Rance, who drops to his knees and pleads for the outlaw to spare him. Jesse accepts and disappears.
Rance soon finds himself back on the set, only to find that his agent is Jesse in Hollywood garb. Jesse insists that the episode be revised so that the actor playing him throws Rance out of a saloon window and escapes instead. To Jesse's satisfaction, the new scene is shot without trouble. As Jesse drives Rance back home, he goes over revisions to future episodes in which Rance fights Jesse's afterlife friends based on what they would really do instead of making Rance look good.
