Other mistake: As the Auron pilot's ship is being brought aboard, a bad scratch on the special effects film briefly creates a large black gash on the hull of Servalan's whale-shaped spaceship. (00:03:05)
Visible crew/equipment: When Avon and Tarrant are consulting Orac about cloning, an equipment shadow crosses Avon's chest. (00:19:20)
Revealing mistake: When Liberator moves into view on Servalan's screen and stops, a bad special effects matte causes the stars behind the ship to keep on sliding to the right. (00:21:35)
