Deep Blue Sea (1999) - 49 mistakes

Continuity: As soon as the three survivors are coming out of the lab through the hatch underwater, they all signal each other to rise to the top. Look at Safron Burrows, her cheeks are full of air and you can almost see the surface above her head. You can also see the exact same shot when she is about to be eaten by the last shark. And what's with that hand gesture - to cut or for the shark to stop?

Revealing: When the sharks first attack and bite off the man's arm - you can clearly see his arm under his shirt as he's scrambling away from the water.

Revealing: At the end of the film, when Preacher is fighting the shark, we can see that it is a white stuntman doing the scene for LL Cool J.

Continuity: In the scene where L.L. Cool J. is in the flooded kitchen and the shark comes in through the door, he climbs up a shelf then falls in the water then climbs out again. Before he makes his way to the oven you can clearly see that under his pants he is wearing knee pads.

Revealing: Near the beginning when the boat pulls up and the guy on the boat tells the blond-convict fella he's got a beauty 13 foot "Tiger shark" that's up in some sort of sling, the so called tiger shark is actually an animatronic great white with stripes on it. Tiger sharks have a blunt rounded nose, not a pointed one like a great white.

Continuity: Towards the end of the movie, the character played by L. L. Cool J stabs the shark through his left eye with his cross, yet in the next scene where the shark returns to eat the female doctor his eye is clearly intact.

Revealing: In the shot when the helicopter is about to crash into the building, take a look at the blade. There is a wire holding the helicopter.

Factual error: A double oven has a double or triple insulating wall between ovens, not a single sheet of flimsy steel.

Factual error: Since the water was always waist high, how could the huge sharks swim inside? Not to mention the corridors...

Factual error: Sharks can swim quite fast (some up to 65kmph). How does Preach, wading at a relatively slow speed, escape the shark the first time he sees it?

Continuity: When McAlister cuts herself and jumps into the water, you see blood in the first shot. Then when she is swimming and wading etc., there is completely no sign of blood at all.

Continuity: When the shark first smashes the glass with the gurney carrying the man who was first bitten who failed to escape on the helicopter, he releases the gurney about 50 feet away from the glass. How could the gurney maintain its speed underwater?

Revealing: When Samuel L. Jackson is attacked and killed by the shark, you can clearly tell that he is CGI. His arms and legs are segments and it looks really corny.

Continuity: When the shark is brought up to put the needle in his head he bites off the guys arm leaving only a bit left there, yet when they are wheeling him to the helicopter you see that he's got more arm than before.

Continuity: When LL Cool J is standing on the shelf and reaching for his bird on the pot, it is clear that he could easily reach the pot if he clenched his fingers. Yet, in the next clip, the pot is shown from a different angle and is at least 1 or 2 feet away.

Continuity: When Carter climbs the ladder to get out of the water after removing the licence plate from the shark's mouth, it shows a shot of his feet and he is wearing sandals. In the tank he was wearing swim fins. He talks to the big boss for a few seconds and the fins are nowhere to be seen. He then walks away with the fins in his hand.

Continuity: Near the end scene, when the three characters came to the surface, L.L. Cool J. was taken by the shark. When he was taken underwater and when he surfaced, the shark had him in her mouth on the right side. When they went under again and resurfaced, L.L.Cool J. was on the left of the shark's mouth. What? Did the shark not like him on the right side so she switched him underwater?

Continuity: Near the end when the survivors has reached the surface and LL Cool J gets attacked by a shark. Notice all the blood in the water. Shortly after, when he is pulled up and rescued, you see no blood at all.

Revealing: As Carter is swimming in the cage under water there is a frontal view of him where you can see the shadow of the camera moving down in the right corner of the screen.

Plot hole: Mako sharks have been known to leap out of the water, sometimes into boats. Therefore, it is quite possible, perhaps even more so, for these specialised Makos to jump.
