Revealing mistake: When Donovan escapes from the L.A. mothership with Robin and the Mexican, he once turns the fighter he is using upside down by mistake. But since the passengers have their heads hanging down then, how come Robin's long hair does not?
V: The Final Battle: Part 2 (2 Hrs) - S1-E4
Revealing mistake: After the failed raid on the Resistance's headquarters, Brian shoots the counterfeiter who led them there, but no scorch mark appears on his victim's shirt (later victims have these scorch marks).
V: The Final Battle: Part 2 (2 Hrs) - S1-E4
Revealing mistake: When Julie is almost converted, a fake Donovan bursts in and starts firing a blaster rifle. Look closely at the first shot: the rifle is held way too high, so the shot should have gone into the ceiling; yet the blast goes straight forward.
V: The Final Battle: Part 3 (2 Hrs) - S1-E5
Revealing mistake: During the final battle in the mothership hangar, Donovan shoots a Visitor soldier who falls off his catwalk onto a transporter. When he impacts, a styrofoam block used to cushion his fall bounces off the roof.
Revealing mistake: During the title sequence when Blair Tefkin's name comes up, Mike Donovan is riding a horse. A Visitor craft passes overhead and shoots at Donovan, but the laser appears out of nowhere instead of from the craft. (00:01:05)
Revealing mistake: When Donovan finds Diana's abandoned car in the desert, the outside shots of the chopper reveal that it is not Marc Singer at the controls. (00:36:40)
Revealing mistake: When Robert and Julie are attacked by snakes outside the cave, notice that in the shots when you see the backs of Robert and Julie there are hardly any snakes on the ground (I counted one) compared to other shots. The shots of Robert's leg as he sweeps the snakes away are almost certainly of a snake handler instead of the actor. (00:37:45)
Revealing mistake: When Ham drives the van through the road barrier, the pieces fall off very easily considering how slowly he was travelling. In the next shot it is shown that the remaining barrier sections are both split vertically, revealing that they were sawed in the same direction beforehand, then the 'broken' pieces loosely affixed before the collision.

The Sanction - S2-E5
Revealing mistake: When Kyle rescues Elizabeth from the theater, if you look closely at his face he has been replaced by a stuntman. (00:12:50)
The Sanction - S2-E5
Revealing mistake: When Klaus skids and falls off his motorbike it is obviously a stuntman as his body is much stouter than the actor's. (00:17:25)
Revealing mistake: When Kyle, Elizabeth and Robin are in the truck being chased by Mr. Chiang, in all the outside shots of the truck it is very easy to see that all three of them have been replaced by doubles. (00:09:05)
Revealing mistake: When Diana offers the ants to the two officers, she is gripping the handle differently between the far shots and the closeup. Needless to say in the far shots the officers are not eating real ants. (00:32:50)
Revealing mistake: When Mr. Chiang does a roundhouse kick against Kyle Bates, he has been replaced by a stuntman. Easiest way to tell is by his hairstyle. (00:37:40)
Revealing mistake: Extremely obvious stunt double for Kyle Bates when he escapes from the clutches of Mr Chiang and jumps off the roof. The stunt double looks absolutely nothing like the actor, and his face is very visible. (00:39:00)
Revealing mistake: When the building explodes at the end, the white limousine parked in front of it completely disappears instead of exploding. (00:45:20)
The Overlord - S2-E7
Revealing mistake: When the girl cuts her hand with the broken bottle, the glass never touches her hand. The blood looks really fake too.
Revealing mistake: When Diana blasts Lydia's shuttle, there is an explosion but the craft is still visible and intact for a brief second. (00:45:20)
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.
