Other mistake: After the stagecoach crashes and Mary discovers that neither Marge nor Adam can move, she tells Adam that she's going to leave the canteen for him and Marge. Neither one can move. Neither one is going to get the canteen to the other.
Other mistake: Vincenzo is looking at a photo of the gorilla Kolchak took of it earlier in the episode. It is a side shot, but Kolchak took two pics when he encountered it, one frontal, and the other shot as the creature was running away from Kolchak and the authorities.
Other mistake: The FBI agents call for a taxi and official transportation from the Evans apartment and gave the address of 963 North Gilbert. However, the Evans lived at 921 North Gilbert. Since the FBI was at their apartment, you would think that they would know the address or exactly where they are in a Chicago project. (00:13:03 - 00:28:29)
Other mistake: The main characters are always clean shaven, the same clothing is worn and their hair never grows from episode to episode.
Rattlers' Class of '63 - S3-E8
Other mistake: Elayne Heilveil portrays Regine in this episode. Her last name is misspelled as "Heilviel" in the opening credits at the start. (00:01:40)
Other mistake: Oscar plays several clips of Steve using his bionic arm, but these shots are taken from earlier episodes in which no CCTV - or any form of surveillance - was present during those moments, making their inclusion here completely implausible.
Other mistake: The interior of the house (excluding the first season), has a door from the kitchen leading outside not far from the front door on the same side of the house and no windows facing that direction, but from the exterior of the house always shown, there is no 2nd door by the front door. Instead, a large window is shown where the kitchen door should be.
