Corrected entry: When the Water and Power boss first sticks the water-sucker into his captain's back, and lets him fall to the ground, he pulls out the device once it's full and walks across the glass-ridden floor, drinking from the bottle. When he pulls out more than just the bottle, it looks like all but the needle-suckers stuck in the captain's back, but in the next shot it's just the bottle. He didn't have time to detach the bottle and get rid of the device.
Corrected entry: In one scene Lori Petty (Tank Girl) is lying chest-down in the sand outside of her house, firing some kind of high-powered rifle at the bad guys, who are in the process of raiding the house. In that scene you can clearly see a hat on her head. She moves and the hat falls off, then we see the house and back to Lori, whose hat is now mysteriously back on her head again.
Corrected entry: When Tank Girl is on guard duty near the beginning of the film, she offers to trade Sam the dangerball for some food. However, she doesn't want to hand over the ball until she gets the food. Then they are attacked and Sam is kidnapped. How does Sam come to have the dangerball later on at Liquid Silver?
