Deep Blue Sea

Continuity mistake: When the shark rises above water with Jan partially in its mouth, its teeth are in about the level of her waist. As Carter grabs onto Jan, it moves its teeth up to the top of her chest. In the wide shot that follows, though, its teeth are back at her waist, then in the last shot of her being pulled underwater, they are up way higher again, at her chest.

Factual error: There's no way those dynamite sticks could have produced anything like the humungous explosion at the end of the film. In fact, the most they would have done would have been putting a hole in the shark's skin. (Proven on Mythbusters.)

Gavin Jackson

Factual error: Without wanting to go into extreme details, the genetics and biochemistry of the entire film is flawed. No geneticist in their right mind would even think about using gene therapy - a technique which is not entirely successful yet - to increase the size of the gland. One would use any of multiple techniques to identify and clone the gene responsible for the protein in question. It is cheaper, more successful, and a lot safer and quicker to do. A copy of the gene could be inserted into E. coli and produced on a mass scale in a beaker on land. After the protein had been isolated it would not be able to be given to patients in a pill form because it would be digested in the gut (like insulin for diabetics). (00:05:20 - 00:48:55)

Continuity mistake: Carter pries open a door with a knife that is on as sheath on his leg. The knife breaks and he throws it away. In the final scene, when Carter and Preacher are laying on the wreckage, the knife is clearly visibly back in the sheath on Carter's right leg. (01:05:00 - 01:37:45)

Factual error: The explosion at the end of the movie should have killed Carter, he simply couldn't have survived the concussion wave.

Continuity mistake: When Preacher, Susan and Carter realise the only way out of Aquatica is to swim and they start filling the room up with water, Preacher holds out his hands to Susan and Carter. Carter then holds his hand out flat for Susan to take, and she puts her hand on top of his. However, in the next shot Susan's hand is on top and Carter's is underneath. (01:25:25)

Continuity mistake: 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. (01:28:20)

Continuity mistake: When Blake and Dr Susan McAlester (Saffron Burrows) emerge to survey the damaged research facility, you can clearly see coastline in the background, although earlier in the movie we see a weather map showing the facility clearly way out in the the ocean. (00:23:25 - 01:29:20)

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.

Continuity mistake: At the beginning, when Dr. McCallister is getting off the helicopter, she is wearing trousers, but when she is talking to Franklin, she is wearing a dress. (00:12:45)

Continuity mistake: When Preacher is talking to the Lord about his wrath, he is in a wide area of the corridor with "Sub Level 1-A" written on the wall behind him. In the next shot he is approaching the wide area with the sign again. (00:42:30)

Continuity mistake: When Carter and Scoggins are under water at the panel you can see light on Scoggins face when the camera is focusing on him. However when it cuts to Carter he is pointing his flashlight away from Scoggins. This happens twice during the shots. (01:13:45)

Continuity mistake: Even though the shark just jumped out of the water and ate the bird, the water is still when the preacher is falling into it. A big shark should make some waves in the water. (00:51:55)

Continuity mistake: In a scene near the end of the movie, Carter is swimming back to the wet lab through flooded passageways. At the beginning of the swim, his left shoe is completely untied - you can see both laces floating. In the next full body shot (where his shoes show) the shoe is tied again. (01:13:30)

Factual error: Late in the film, Susan is wearing rubber aquatic shoes. She goes to her quarters to retrieve the data and decides to electrocute the shark that attacks her. She takes off her rubber wetsuit and stands on it on the metal table to insulate her from the current so she doesn't get electrocuted herself. But, isn't she already insulated by the rubber on the bottom of her shoes? Was this just a reason to get her to take her clothes off?

Revealing mistake: In the wet lab, just after the helicopter explodes into the tower, pieces of concrete are falling all around Thomas Jane, as he reaches to pull the blonde out of the water. The pieces of 'concrete' bounce all around like the foam pieces they are, not actual concrete.

Factual error: When the rescue helicopter approaches Aquatica, the pilot gives his call sign as "X-ray Alpha two eighteen." Numbers in aviation are read individually, so the pilot should have said "X-ray Alpha two one eight."

Visible crew/equipment: When Preacher falls off the shelving rack into the the water after his bird was eaten by the shark, you can clearly make out the zip for his wetsuit under his jacket. (00:52:00)

Continuity mistake: At the end, Carter manages to hold onto the perimeter fence, and the shark goes through. The shark then explodes, and Carter is seen being blown off the fence back the way he came, yet when he surfaces, he's now on the other side of the fence.

Visible crew/equipment: After Preacher says "Feeding time" and the camera moves toward the window, you can see the camera's shadow down in the left corner of the screen. (00:16:55)

Russell Franklin: You think water moves fast? You should see ice. It moves like it has a mind. Like it knows it killed the world once and got a taste for murder. After the avalanche, it took us a week to climb out. Now, I don't know exactly when we turned on each other, but I know that seven of us survived the slide... And only five made it out. Now we took an oath, that I'm breaking now. We said we'd say it was the snow that killed the other two, but it wasn't. Nature is lethal but it doesn't hold a candle to man.

Trivia: All three sharks are killed in almost the same way the first three sharks is killed in the 'Jaws' movies. Blown up with gas, electrocuted and the last one is blown up.

More trivia for Deep Blue Sea

Question: I know that Susan was originally supposed to survive and kill the last shark but the test audience greatly disapproved of this. Why did the test audience hate the original ending? And why is this ending unavailable to watch?

Answer: Audiences viewed Susan as a villain of sorts, because all the mayhem and deaths in the film are a direct result of her breaching protocol, so they decided to rewrite the ending to have her die. As for why it's unavailable to view, perhaps the filmmakers didn't think people would be interested in seeing it.
