The Night of the Underground Terror - S3-E19
Factual error: The episode opens in New Orleans during Mardi Gras, circa approximately 1873. We hear a jazz band playing "When The Saints Go Marching In" although the song didn't emerge in a recognizable form until the end of the 19th century. (00:00:19)
The Night of the Turncoat - S3-E13
Visible crew/equipment: As West is swimming in the water tank that is filled with dangerous sea creatures (Hammerhead sharks, etc.) a modern day (1960's) frogman is swimming behind West in the tank.
The Night of the Skulls - S2-E13
Revealing mistake: In the livery stable fight scene between Gordon and Tigo, the tines of the pitchfork Tigo threatens Gordon with wobble, indicating they are made of rubber or a soft material and not metal.
The Night of the Gruesome Games - S4-E5
Revealing mistake: Just before Doctor Raker gets to the cliff before falling, there is a jet airliner seen in the sky just over his right shoulder.
The Night of the Underground Terror - S3-E19
Revealing mistake: After West shoots Major Hazard on the water tower, the falling stuntman lands on a safety cushion that is about a half foot below the ground surface. Further, the next scene cut shows Major Hazard being covered by the tower contents, but Hazard is now lying on the ground surface, not below it like the stuntman.
The Night of the Amnesiac - S3-E22
Continuity mistake: As Gordon interrogates Crotty, Crotty raises his cigar to his face twice.
The Night of the Flying Pie Plate - S2-E6
Revealing mistake: When the townspeople spill out onto the town's streets after hearing the noise from the sky, the horses tied at the hitching posts never move nor flinch through the entire scene and are all in the same pose, indicating the horses are props and not real.
The Night of the Amnesiac - S3-E22
Continuity mistake: When amnesiac West emerges from between the buildings, it is dark outside, but when he encounters the cowboy assaulting the woman, it is now suddenly broad daylight.
