Continuity mistake: When the Red Dust is spread, there is a brief shot of some California citizens watching, and we see the Bernsteins among them. But the actress at George Mofogen/Mr. Bernstein's side is not Bonnie Bartlett, who played Mrs. Bernstein in the first two episodes.
Continuity mistake: When Diana is being chased by Donovan after crashing her craft, she has her normal human eyes. But during Donovan's strangulation attempt she has lizard eyes. As we saw in the original series, a Visitor's human eyes had to be removed by hand before the lizard eyes could be seen underneath.
Continuity mistake: After a talk with Diana on the mothership, Lydia is left alone and then she takes a message out of her uniform. She wears a ring on her left middle finger and her nails are painted red. In the following shot we see Lydia's hands put the message into a box. The hands do not have their nails painted and wear no ring whatsoever.
Continuity mistake: When Julie and Robert infiltrate the hospital using the forged passes, the pass is shown twice as it is inserted into the reader. In the first shot, it slides in down whole, but the reader is still buzzing. In the second, the card starts sliding in again.
Continuity mistake: When the spaceship is hovering overhead, we see various shots of the Maxwell family and others. In one shot we see the family from behind with a person in blue. We then jump to a shot from the front with that person not in picture. We then go to another behind shot and see the same person hurriedly moving into shot.
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.
Continuity mistake: When the heroes are trying to blast open the bridge door, Elias knocks the shell of the explosive off with the butt of his laser rifle, bending it. When they rush onto the bridge a moment later, the stock is straight again.
