Plot hole: During the entire standoff between Blake & Travis, there is a Federation guard with his hands on his head. Yet when the scene first begins, no-one else is and Blake is not holding a weapon on anyone. Neither has he revealed his play with the virus at this point. After he has done so and left, the same guard still has his hands up. Finally, after Travis has secured the virus, the guard STILL has his hands up.
Visible crew/equipment: Avon is picking himself up from the computer room floor after a berserk Gan has attacked him. Blake rushes in to say, "Are you all right?" But he's been standing out there in the corridor, blocking a big bright patch of light throughout the scene, only to rush in on cue. (00:26:10)
Plot hole: When Blake teleports to XK72 to meet Professor Kane, he takes 2 teleport bracelets so that Kane can return to Liberator with him. When Avon goes over to retrieve the medical assistant, he neglects to take an extra bracelet. The assistant beams over with one anyway, and Avon somehow still has a bracelet to return with later. (00:34:05 - 00:41:30)
Revealing mistake: A very poorly executed special effects matte causes the star patterns behind the 3 pursuit ships to slide in opposing directions at the same time. (00:42:35)
Continuity mistake: The XK72 space station has a distinctive shape, with a large ringed aft section that's to the right of the screen every time we see it. Liberator is moving past that section at the end, passing on the right. But in the next shot, the ship is abruptly heading away from the station, which is still in the same position, and flying left, in the opposite direction. (00:47:15)
Factual error: Zen refers to the objects encountered at the beginning of the episode as "meteorites". In space, these objects are known as meteoroids. When they enter the Earth's atmosphere they are called meteors, and when they hit the surface of the earth they are called meteorites.
Continuity mistake: Liberator's orientation relative to the space station changes. As viewed from inside the administrator's office, the ship is "parked" parallel, with its port side against the station. But in the subsequent exterior view, Liberator suddenly has its bow pointed directly at the station instead.
Visible crew/equipment: When Jenna asks Gan to keep trying voice contact with the unidentified ship, the boom shadow is distinctly outlined on the control console to the left of the shot. (00:08:00)
Visible crew/equipment: When Sarkoff puts a record on his antique phonograph, the metal desk behind him reflects a camera dolly rolling by. (00:25:50)
Visible crew/equipment: Sarkoff holds his Plexiglas/Perspex butterfly case up to admire it, and captures a perfect image of one of the set's large rectangular light reflectors. (00:28:15)
Revealing mistake: The explosive collar supposedly locked around Blake's neck is undone and hanging open just after he's thrown into the cell with the other prisoners. (00:33:45)
Deliverance - S1-E12
Visible crew/equipment: When Avon says, "It could have been a power unit burnout," a boom shadow moves quickly across the bottom of the screen. (00:04:05)
Deliverance - S1-E12
Visible crew/equipment: During Zen's report on the planet conditions, an equipment shadow is visible on the flight couch at the lower right of the screen. (00:07:05)
Deliverance - S1-E12
Continuity mistake: Meegat peeks at the rocket through the oval space Gan has cleaned on the dirty glass. The shape of this space changes dramatically when the camera angle switches to the other side of the pane. (00:39:15)
Revealing mistake: As Liberator approaches it, the planet changes color. (00:08:05 - 00:13:40)
Revealing mistake: When the "phibian" lizard creature attacks Servalan, note the claw that grabs her leg: it is obviously made out of soft fabric and visibly bends as it latches on. (00:24:05)
Visible crew/equipment: When Avon calls and wakes Vila up, ordering him to the teleport room, you can see Vila, who's supposed to be in his quarters at this point, hiding in the corridor waiting for his cue. (00:40:50)
Plot hole: When the newly-acquired Orac is first set up on the flight deck, Blake comments that "the other end's connected." Connected to what? Orac didn't require plugging in, other than putting his activator key in place, and that was never connected to anything else. (00:46:45)
