Factual error: Servalan's ship takes off from the surface of Bucol 2 with Avon and crew standing directly below it. Yet for some reason, the down-blast from the very large launching ship does nothing more harmful than slightly mess up their hairdos.

Revealing: The Federation Commander reads a report to Servalan, but when the camera angle shifts to a shot taken over his shoulder, you can see that he's "reading" from a colorful plastic board with no printing on it whatsoever.

Continuity: When Avon & Co. barnstorm the ruined lab, a large piece of plastic debris on the floor is there when they enter, but then disappears between takes. Avon actually slips on it coming in, and does a hilariously un-macho little balancing dance. To quote (and agree with) actor Paul Darrow: "I can't believe they left that in!"

Continuity: Maybe he ran into a barber along the way? Avon beams into the woods on Bucol 2 with his hair brushed straight back, but a few shots later, it's restyled and combed neatly down over his forehead.
