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. (00:11:15)
Revealing mistake: 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. (00:22:20)
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. (00:33:30)
Revealing mistake: When Scorpio flies from its launch bay cut in the Xenon cliff face, it's broad daylight (and no, the planet does not have twin suns) - but the ship casts a shadow on the cliff above itself. There's no possible light source from that angle other than studio lights on the ship model. (00:01:20)
Revealing mistake: Scorpio is attacked upon entering Gauda Prime's atmosphere. The ship lurches left: everyone leans left and hangs on. The ship lurches right: everyone leans right and hangs on. The ship rolls over a full 360 degrees: no one leans or hangs on, nor do they fall out of their unbelted flight chairs. And oddly, those same chairs that held fast here tip over with ease later, when Avon escapes with Orac. (00:13:45 - 00:16:15)
Continuity mistake: Just before Scorpio crashes, Avon grabs Orac and teleports to safety. When they're still aboard the ship, Orac has several wires hanging loose from underneath. When they materialize on the planet, however, all the loose wires are magically repaired and no longer hanging. (00:16:30 - 00:17:45)
Revealing mistake: Avon & Co. are supposedly racing through the woods and cloudy skies of Gauda Prime in a flyer. But the reflections on the vehicle's windscreen never move. (00:38:45)
