When Taarna examines an evil "S" medallion on the hitched bats outside the bar, it is reversed to a "Z" when she first walks up to it. As she grabs the medallion, it goes back to the correct "S" shape.

The two final scenes of "So Beautiful, So Dangerous" are reversed. The robot and the secretary exit the ship onto the space station before the ship lands. If you look closely at the lower right corner of the screen as the ship grinds to a halt in the hangar bay, the escalator ramp used by the robot and the secretary only seconds before is deployed.
