Visible crew/equipment: After Calvin Bouchard makes the announcement to tourists visiting the Undersea Kingdom to evacuate, we see the tour guide lead the crowd through the tunnels. The green screen backdrop is still in the final cut. They forgot to add in the underwater effect.

Factual error: The scene where the Shark is in the water/air circulation pump it swims backwards out of it. There is no way a shark could do that, it would drown.

Factual error: When the shark swims towards the glass, it doesn't move it's tail. Sharks have to swing their tail in order to swim. There is no way this shark could be moving.

Visible crew/equipment: In the opening credits we see shots of water skiers climbing on top of each other to try and form a human pyramid. In one long shot you can see the side of the wake which the crew’s speedboat is making. (Timecode) Submitted by Hamster

Continuity: When two divers emerge from the water, one pulls their goggles up onto their forehead and the other pulls his goggles down to round his neck. Then the divers and Mike start talking about ‘no overtime’, and between shots the goggles around the divers neck vanish. (Timecode) Submitted by Hamster

Factual error: When the shark is chasing Mike and his girlfriend near the end you can see air bubbles coming out of the fin (obviously a hole in the puppet). Real sharks do not blow bubbles from their fins.

Factual error: At the end of the movie, the shark broke through the glass. When the entire room was flooded, the shark grabbed someone and started chewing them. Sharks don't chew their food. If their prey is too large to swallow whole, they rip it apart into smaller pieces.

Revealing: When the baby shark smashes into the gate, not only is it a dummy by the way it looks, but the head actually compresses back into the body on impact.

Factual error: The window in the underwater control room has to be made from some thick material such as plexiglas to stand the pressure. Yet the shark simply lifts its snout a little and sends thin pieces of glass shattering everywhere.

Visible crew/equipment: When Mike fires the harpoon at the shark, the wire the arrow is attached to is visible. (Timecode) Submitted by Mortug

Continuity: When Mike answers the call from Calvin the phone cord goes over his shoulder. When it cuts it's gone. (Timecode) Submitted by Mortug

Continuity: When Dan walks down to a podium and looks over to see the dolphin knocking at the gate, the tee-shirt he is wearing changes from being plain white with a tag badge on his left, to a white shirt with a large blue stripe across it, with a tag badge being on the right.

Continuity: When the shark has chased Mike and Catherine they get back into the space where they go in and out to the water. The room is completely filled with water. We see Mike's hands turning the vent-things (I don't know the proper words for them) to let the water out, only problem is his hands are not IN water. They are in air, not a drop of water in sight. Then we see the room emptying of water and Mike and Catherine are both still in water. Mike's hands should have been underwater in every shot of the scene up until then. It's obvious that the hands were Mike's as you could see his wet suit.

Continuity: When the shark is chasing the water-skiers, you can see its fin is about 3 feet behind them, meaning its head must be underneath, if not in front of them. However, in the shot from under the water its viewpoint is shown as being behind them.

Continuity: When Mike has the harpoon pointed for the sharks dorsal fin, there is white rope wound around the length of the metal harpoon. In the shot just before he shots the harpoon, there isn’t. Submitted by Hamster

Factual error: In the scene near the beginning of the film where a diver gets eaten by the shark, an unattached arm is left suspended in the water. Not one drop of blood was spilt into this water.

Factual error: In the scene where they try to lure the shark, it eats that man. How is it possible to fit in a shark's mouth when only someone's leg did before? Also, if you look outside the shark's mouth, it isn't going anywhere, which is also impossible.

Revealing: The shark attacks a little wooden platform in the water which 3 men then fall through. You can see this is made from a lightweight wood such as balsa so that it will break apart easily, and it's not the sort of wood such a thing should be made of.

Continuity: In the opening credits, there are eleven skiers in the pyramid. However when they fall in the water, and then all get up and ski off again, there are only ten skiers now. (Timecode) Submitted by Hamster

Revealing: As Mike and Kathryn are underwater with the submarine, they pass the control room, and in the next shot, as the submarine turns around, the front of it suddenly goes transparent. Submitted by Mortug
