The Night Dr. Loveless Died - S3-E4
Continuity mistake: In the opening scene, a cowboy sitting atop the balcony above Big Brad's Bar gets up and approaches the balcony's edge twice.
The Wild Wild West (1965)
Starring: Robert Conrad, Dick Cangey, Ross Martin, Whitey Hughes
The Night of the Bubbling Death - S3-E1
Revealing mistake: As West drags the body of a bad guy out of the scene, the supposedly unconscious man is holding his head up so as not to have his head dragged through the dirt. A truly unconscious person's head would flop back on to the ground.
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.
The Night Dr. Loveless Died - S3-E4
Trivia: Dr. Loveless' uncle's name, "Liebknicht", is, aside from the addition of the letter "k", German for "Loveless".
The Night of the Infernal Machine - S2-E14
Trivia: West collides with the cook and sends him sprawling face-down in a huge platter of gelatin. Before racing off again, West quips, "Sorry about that, chef!" This was a winking homage to the 60s spy comedy Get Smart and its bumbling hero Maxwell Smart's famous catch-phrase, "Sorry about that, Chief!" (00:47:30)
