Revealing mistake: The two Elizabeths are both played by the same actress, except in the shots where both are seen together. Continuity mistakes in the second Elizabeth's death scene reveal this, such as the second Elizabeth's head position changing, and the first Elizabeth's jacket being open/closed between shots. (00:42:30)
Deliberate mistake: The shot of the mothership landing bay and the arrival of Charles' ship is stock footage that has been used several times before. There is also a continuity error here - the view from the landing bay shows darkness outside, but the next shot shows broad daylight. (00:06:20)
Continuity mistake: When Chris and Ham are sitting down talking about The Conversion process, Ham gets up and walks over to the map. When he turns around Chris is suddenly standing in front of him, whereas he should still be sitting down. (00:37:35)
Revealing mistake: Several times during the Charles v Mike fight scene it is obvious that Charles has been replaced by a stunt double. (00:43:50)
Deliberate mistake: The shot of Willy running away from the parked car is taken from the episode where Elias is killed. Two things give this away - 1) Willy is wearing a different coloured jacket and 2) he is supposed to be seriously injured yet he sprints along the street. (00:08:50)
Continuity mistake: When Charles reads the message about Nathan Bates coming out of the coma, there are two things to look for during the closeup of the note. The logo on the top is replaced by writing and he grips the note in a different position from before. The writing changes yet again when the note is seen from behind. (00:13:35)
Audio problem: When Ham grabs Howie's armband and says 'our man' it's painfully obvious that the words have been dubbed by Marc Singer instead of Michael Ironside. (00:19:00)
Revealing mistake: When John is holding the two mice, if you watch his left arm closely you can see his arm jerk beneath the table where he replaces the real mouse with an edible one. (00:20:50)
Continuity mistake: When Willie dies, Howie says 'he's gone' but Willie's head position changes between shots. (00:24:55)
The Rescue - S2-E13
Visible crew/equipment: The boom mike is visible at the top of the screen shortly after James starts talking to Diana in the mothership control room. (00:04:05)
Plot hole: In the opening scene we see Mike and Kyle driving in the truck. Kyle remarks that Mike has been driving since midnight and it is broad daylight outside. So they have supposedly been driving for several hours. Yet they start talking about their mission as if they have only just got in to the truck. As anyone who has been in that kind of situation knows, everyone always discusses the important stuff at the start of the journey, so it is clear that the scene has been poorly scripted. (00:02:00)
Revealing mistake: An obvious stunt double replaces Marc Singer when he kicks the sheriff's shotgun out of his hand, and also when the truck drives into the lake. (00:05:10)
Visible crew/equipment: The boom mike is briefly visible at the top of the screen when the woman on the horse rides up to Mike and Kyle. (00:06:10)
Revealing mistake: When James' craft touches down outside the Sheriff's office, the wires suspending it from above are visible. (00:33:50)
Continuity mistake: Mike Donovan (riding a horse) is chased by a Visitor shuttle. It is obvious that there were recycled some shots from "The Final Battle" (Ep. 1). In "The Champion", Donovan does not have a laser pistol. However, there are some shots in which he has that pistol: obviously, those shots are taken from TFB.
Revealing mistake: When the two wildcats throw hand grenades at the Visitors, the grenades are obviously fake because the explosions do not occur at the same place as where the grenades land. The detonations have obviously been located in a safe place away from the actors. (00:11:50)
Visible crew/equipment: When Julie says 'We're gonna stand and fight' near the end of the episode, a boom mike briefly creeps into view at the top of the screen. (00:42:15)
Continuity mistake: When Philip is first seen with the metal thing on his lens a buzzing sound is heard. Afterwards, no buzzing sound is heard. (00:17:10)
Continuity mistake: When Kyle is with Donovan in the warehouse shooting at Philip, you always hear a bang coming out of the machine gun but sometimes a fire blast is not seen.
