Continuity mistake: Batman deals with one of the jewelry robbers pulling him out of the car. Robin uses the bat-rope to grab the one that is running away; when he's running, just before he's caught by the rope he passes by a manhole to his right. When Robin's gun drags him throughout street, the manhole is on his left.(00:10:15)
Trivia: While Mr. Freeze is at Shaugnessy's, when Shaka smacks Dick across the room, he ends up flat on his back, and in the close-up when Dick raises his head, the buttons on his vest switch sides momentarily. Then the buttons revert back (noted in trivia because it's better when clicked through slowly).(00:24:25)
