Visible crew/equipment: As the shuttle pod lands on the planet with Elle and Stella, you can see the reflection of some member of the crew wandering around off camera.
Revealing mistake: As the huge guardian goes to move off and chase Elle and Stella, you can see its shadow cast on the fake backdrop sky.
Continuity mistake: Count Zarth Arn discovers Simon, Stella and Akton in the computer room, and he stands in the doorway. In the next two shots, it shows soldiers on both sides of the room, and in both shots, the doorway is now empty.
Continuity mistake: When Stella is put into the machine to revive her after being frozen, her head is tilted to the right when she goes in, but is tilted to the left when the shot changes.
