Continuity mistake: When the mimes open fire on the gangsters, watch the police officers to the left and right above them on the top of the steps. In the overhead shot, right after they open fire, they disappear. (00:49:30)

Revealing mistake: When the shields of the Batmobile are engaged, the metal plates come from nowhere. There isn't a place for them to come from or go to when taken off. And if you watch carefully, the shields coming from the sides of the Batmobile come out of thin air. (01:09:10)

Continuity mistake: 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 mistake: When the Joker is shooting Carl Grissom wildly, you can hear the sound of the glass behind him being hit only once. Later when the Joker is sitting at his desk, you can see two bullet holes to the left in the glass.
