Stage West - S1-E6
Factual error: In the background, in the scene when Simmons is talking to the stage driver, you can see cars driving by on a road in the background. (00:12:06)
Character mistake: Bret fires at "John Wesley Hardin" four times, but the doctor and all the witnesses say there were three shots.
Bret: My Pappy always said, "A coward dies a thousand deaths, a hero dies but one." A thousand to one is pretty good odds.
