Visible crew/equipment: When Heyes and Curry leave the saloon and walk across the street, a microphone mounted on the camera rigging pops up into the shot at the bottom of the frame and follows along beside them. (This is visible in the US aired and vhs versions, but was edited out of both the BBC version and the recent dvd release.)
Plot hole: Early in the episode, the sheriff starts going through his pile of wanted posters. According to the story line, 18 days then pass. At the end, the sheriff, standing in the exact same position and wearing the same clothes, is just finishing his search through the posters.
