Revealing mistake: When Rocky climbs the RKO tower, he carries lifeless Frank-N-Furter on his back. In the wideshots facing the stunt doubles' backs, while Rocky has both of his hands on the tower, the very much dead Frank-N-Furter has his right arm firmly around Rocky's neck to hang on.

Revealing mistake: When Troy crouches down on the rocks, and leans down to see his reflection in the water, oddly the reflection is not reversed, yet his hair is combed the opposite way. (Did the director actually think that if Troy's hair was combed the opposite way it would pass as a reversed reflection?) Additionally, when he crouches down, the bottom button on Troy's shirt is unbuttoned, but in the reflection (as well as in the previous and following shots) the bottom button is buttoned up.
Revealing mistake: As the grating descends on Raoul, in two shots, large bubbles are flowing downwards. It's obvious, the film was reversed. (01:59:15)

Revealing mistake: When the elephants are making fun of Dumbo in the train caboose, Dumbo's mother pulls a pin which causes the stall door above the other elephants to fall. When the door bounces back up, you can see that the animators forgot to draw the elephants' heads and trunks and only their bodies are visible.
Revealing mistake: After Mitchie wakes up at the start, her hand slides across the keyboard keys in the close-up, but that hand is not Demi Lovato's. The older looking hand has protruding veins and the fingernails are long, whereas Mitchie's nails are short and her hands look as young as she does.
