Revealing: 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.

Continuity: 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.

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.

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: 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.

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.

Revealing: When Avon is calling for teleport from the space station, Cally's reflection on the Liberator's shiny corridor wall reveals that she's standing and waiting for her cue to rush into the teleport room.

Visible crew/equipment: When Zarkov puts a record on his antique phonograph, the metal desk behind him reflects a camera dolly rolling by.

Visible crew/equipment: Zarkov 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.

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.

Revealing: 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.

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.

Continuity: 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.

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.

Deliberate "mistake": Because Stephen Greif tore an Achilles tendon playing squash, a stand-in had to complete his scene with Servalan in Ensor's underground complex. The result was a very odd segment in which we hear Travis' voice (pre-recorded by Greif) answering Servalan's lines, but never see him - except for an awkward shot of shuffling, black-booted feet that are all-too-obviously not Greif's.

Visible crew/equipment: At the end, when Blake says "The other end is connected," the boom shadow crosses Avon's face.

Revealing: As Liberator approaches it, the planet changes color.

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.

Continuity: When Cally puts her teleport bracelet on in the teleport room, it's on her right wrist. After she and Blake materialize on the planet's surface, the bracelet has mysteriously moved to her left wrist instead.

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.
