Visible crew/equipment: Someone with a mustache moves briefly into the shot behind Avon when he's questioning the android about its plan to unite with Orac.

Revealing: After its "borrowed" head is blown off and it rampages through the base headless, the android mysteriously gains 10 inches in height and has much longer arms. If they'd just found a shorter actor to wear the headless costume, it might have looked more convincing.

Revealing: When Avon pushes a button to call Tarrant, the entire control panel tips upward, revealing that it's not anchored to the console at all.

Continuity: Muller and Vila have a brief struggle over the teleport console. When Muller grabs at the controls, Vila pulls his hand away, making the teleport lever break off and fall onto the console. It fixes itself again a short time later.

Visible crew/equipment: When Nebrox is relaxing in a chair on Scorpio's flight deck, large bright yellow power cables are visible running from the console behind him and across the set floor to the right of the shot. Maybe they were jump starting the space ship?

Other: The number of buttons on the left shoulder of Tarrant's costume keeps changing throughout this episode. Most of the time, all 4 are there, but in several intermittent shots, one of the buttons is missing.

Visible crew/equipment: While pulling back from Vila's conversation with the gaming computer, the camera apparently runs over a cable. There's a visible jump in the picture and an audible clanking noise.

Revealing: The dead man, shot by the game computer in the orbiter's corridor, is still moving his fingers, and later moves his arm from resting on his chest to flat on the floor.

Continuity: Orac is in two places at once: he's sitting on the console, plainly visible in front of Dayna as she calls the landing party - but in the next shot of the crew over on the orbiter, Vila is holding Orac.

Continuity: The computer simulation shoots Gerren in the left shoulder, but when the Scorpio crew teleport him up to let Soolin render first aid, he's holding his right shoulder instead.

Revealing: At the end, when Tarrant is beamed out, Servalan's position shifts considerably, even though she's supposedly standing still.

Continuity: When Dayna and Tarrant find Keeler unconscious, Tarrant's teleport bracelet disappears between shots. It's back a few shots later, though.

Continuity: Tarrant beams down to the refinery complex and back again without a teleport bracelet.

Revealing: Avon and Soolin hide from the processing plant guards in an alcove, but Avon's black-booted foot is sticking out in plain sight. Fortunately, the guards don't seem to notice and walk on by anyway.

Revealing: Scorpio is in stationary orbit over the planet Malodaar - but a shaky special effects matte causes the "stationary" ship to wiggle and wobble severely.

Factual error: Maybe they took time in the midst of a desperate escape to tack Orac down with Velcro? When the shuttle first takes off, its angle of ascent causes Orac to nearly slide off the control panel. A short time later, the angle is far steeper, but this time Orac stays perfectly still.

Revealing: A shot of Scorpio en route to Betafarl falls victim to a special effects problem. The camera shooting the model was apparently bumped and shaken, so the ship is suddenly wobbling so badly it's a wonder it can keep a straight course.

Plot hole: Ordered to kill him, the Federation squadron stakes Avon down - on a sand dune. Naturally, he has no trouble pulling loose and clobbering them all. This is hardly just a "character choice": it's a plot hole the size of Tuskeegee. A trained military unit (which they were) would never be so stupid. They could simply have shot him with no difficulty whatsoever.

Plot hole: When the warlords lift their glasses in a toast, the same mysterious blue electrical arcs, which later appear and kill everyone in the freight bay, spark and sizzle around their hands. But for some strange reason, no one seems to find this at all peculiar.

Revealing: A bad effects matte causes one of the two ships approaching Xenon to partially dissolve along the way.
