Continuity mistake: When the Batmobile is going to park (before the bomb scene) there is a sign saying "Mobey Dick Parking Only". When he is later carrying the bomb and passes by the Batmobile the sign is not there.
Revealing mistake: When the Penguin is sliding down the zip line, just before he hits Batman you can see Batman throwing a punch at nobody, he is swinging at empty air.
Continuity mistake: When Bruce Wayne escapes from the United Underworld (Joker, Penguin, Riddler and Catwoman), he climbs to the top of their hideout (Ye Olde Benbow Taverne) and jumps from the top of the roof (to the water below). But in the next shot, Bruce now jumps from the edge of the roof and dives into the water. (00:54:20)
Continuity mistake: Near the end of the film we visit the office where the country representatives had argued earlier. Batman sets up the chemical equipment to bring them back. When it's done, where has the equipment on the seats gone?
Other mistake: Robin yells "Holy Polaris" before the rocket even breaks the surface of the water.
Other mistake: When the Riddler fires a missile near the end of the movie it curves to the left. The writing on the missile is backwards, showing that it is reversed footage from earlier in the film, when it curved to the right. (01:21:00)
Revealing mistake: In the first shot of Adam West and Burt Ward driving in a beige '66 Imperial convertible, the camera zooms out above the car - but not before you can see that the two men in the car are stand-ins for Adam and Burt.
Revealing mistake: Batman is lowered into the ocean and a shark attacks his leg. When Robin in the Batcopter pulls both Batman and the shark up out of the water, the very fake looking shark has gallons of water pouring out the back of it where there must have been a large hole.
Other mistake: The scene where the Penguin is dehydrating his henchmen. Watch as the last henchmen is dehydrated - the shot changes to the Penguin and the Riddler. You hear the Riddler's laugh but his lips don't move until the end of the laugh.
Continuity mistake: During the fight on the submarine, just before Robin punches the Joker into the water there is nobody else on the deck. When the Joker is shown falling overboard, two other henchmen are sprawled out on the deck near him.
Continuity mistake: When Robin is saving Batman from the shark, and he is hanging upside down to spray the shark repellent, his position in relation to Batman changes between shots (almost too far to reach, then he is suddenly close).
Continuity mistake: When Batman discovers a bomb, he is driving towards the villain's hide out and you can see all the parking spaces are full except one, yet when he parks there are no cars on either side of him.
Continuity mistake: In the helicopter scene in the first 10 minutes of the movie, Batman moves down on the ladder and stops. In that first shot you can see that there are about 10-12 rungs below him. In the next shot there are only two. Shortly after he gets attacked by the shark there are now at least four rungs below him, and yet he has not made any attempt to move up or down.
Other mistake: When Penguin and the others attack Bruce on his date in his hotel room, Penguin is the first one to charge him. Bruce takes a swing at Penguin's face and he goes flying from the blow. You don't even need to slow the film down to see that Bruce totally misses him.
Revealing mistake: When the Batboat leaves the dock, heading out to sea, the blurred rotors of the camera helicopter are constantly seen across the top of the shot. (00:20:40)
Continuity mistake: The amounts of colored powder in the vials change in every shot; sometimes they are all equal, other times there are large differences between them.
Other mistake: When the Batboat is approaching the submarine before the final fight, the shot from the periscope is an overhead shot, not a surface shot like all the others in the film.
Continuity mistake: When Batman and Robin are trapped on the buoy, they can see the periscope for the submarine sticking above the water, yet whenever a torpedo is launched, it is shown approaching from a distance much further away.
Other mistake: When Bruce Wayne enters Wayne manor after his escape from the criminal hideout, Bruce opens the door and closes it, but it doesn't latch. The door starts to swing open and then suddenly closes, as if a stage hand was there to close it. (00:54:35)
Revealing mistake: Whenever the moving Batmobile is emitting flames from the afterburner, like when it leaves the Batcave for the first time, an object is hung below the exhaust port that resembles a camcorder. The gadget is part of the equipment added to make the car shoot flames while moving. During the TV series, flames are only seen in close-up of the car motionless, as this was a prop comprised of a copy of just the last few feet of the car. On TV, the car's rear license plate is visible. In this film, it's partially blocked by the added equipment. (00:03:35)
Answer: The Riddler doesn't sing at all. He yells to the henchmen on board, "Prepare to repell boarders!" He does it in a almost musical way, true, but there's no song.
