Continuity: After Batman rescues Vicky he has a voice remote for the Batmobile. As the car approaches he orders the car to stop by speaking into the remote and then lowers it to his side. When the camera shot changes showing the car stopping right in front of him, he is still holding the remote to his mouth. (Time)

Continuity: In the scene where the Joker's henchmen are trashing the museum, one guy puts purple handprints all over a portrait, later the Joker walks by the same portrait and the handprints are gone. (Time)

Visible crew/equipment: When the Batmobile is driving itself to Batman and Vicky Vale, you can clearly see a hand turning the steering wheel. (Time)

Continuity: During the beginning of the parade sequence, the green-haired, big-nosed balloon is shown being decently high with the Joker's float underneath it. Yet when the Joker is shown dancing in a few close up shots, the face of the balloon is directly behind him.

Continuity: In the scene where the "automated" Batmobile is sent into Axis Chemicals to blow it up, six of the Joker's men are shooting at it. Three of these same henchmen are also on the Joker's parade float at the very same time in Gotham Plaza and one of them flies the Joker's escape copter at the end of the movie.

Continuity: When Joker is at the top of the building and taunting them, his chin is red (presumably from his blood when Batman socked him in the jaw.) After he falls off the building, and we see him lying on the ground, his chin is not covered in blood like it was before. (Time)
