Continuity mistake: When Lori is shoved down the pipe, check out the close-ups as she slides down. At least twice she has one blue eye and one green eye - though her eyes are blue in every other scene.
Continuity mistake: The Tank alternates between having a silver machine gun to not having one, to having an Uzi 9mm, to having a 40 caliber.
Visible crew/equipment: After the fight between Water and Power and the reapers, once Tank girl lights her stick on the flare stuck in the corpse's mouth, an ordinary car can be seen slowly moving about in the background for a brief moment.
Other mistake: The first time Rebecca gets Keslee's arm stuck, he wipes his head with his hand, but she goes to punch him, her hand passes through the hologram. His hand should have gone through as well. Also, when she shoots the bucket at the end, it dumps water on him, and he coughs, though the water shouldn't have bothered him.Movie Nut
