Other mistake: "Night of the Bubbling Death": When West lifts the unconscious bad guy by the shoulders and prepares to drag him out of sight, you can see drag marks already in the dirt from previous takes. (00:21:10)
The Wild Wild West (1965)
1 other mistake in show generally
Starring: Robert Conrad, Dick Cangey, Ross Martin, Whitey Hughes
The Night of the Avaricious Actuary - S4-E11
Continuity mistake: The letter from the Cyclops Insurance Company that Gordon pulls out of his pocket is folded, wrinkled, and well-worn. In the close up of the same letter West reads, the letter is white, pristine, and not wrinkled or folded.
Trivia: Due to the rigorous stunts he performed, actor Robert Conrad would often rip out the seat of his already too tight pants.
