Deep Blue Sea

Continuity mistake: While Carter is trying to save Jane, he is a few feet above the water. But in a shot from above you can see that he has to bend his body so as not to touch the surface. It would be very easy for him to reach her. But in the next shot, he's high above the water again. (01:06:25)

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)

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)

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

GalahadFairlight

Continuity mistake: 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. (00:08:55 - 00:10:20)

Plot hole: Considering the size and power of the sharks, why didn't the female just jump the fence at the end of the film. It was only 3 or 4 feet above the water at that point. (01:30:10)

Grumpy Scot

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)

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: 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)

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)

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."

nightshade01

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)

chakorn1

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)

Ssiscool

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: 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)

Mortug

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)

Mortug

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)

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.

GalahadFairlight

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)

Mortug

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.

Question: Was there supposed to be some more of the scene between Carter and Susan after she had killed the third shark?

Answer: I assume you are referring to the scene after Susan killed the second shark (she was killed before the third shark was killed). The comments LL makes to finish that scene do seem a little out of place with what they were talking about but the film does have a number of scenes cut out. Most of the deleted scenes on the DVD deal with character development and dialogue but there is no evidence the scene was cut as the DVD's deleted scenes dont have any extra footage on that scene or alternate dialogue.

Lummie

Answer: Yes, Susan and Carter actually share a kiss in the original ending. They grew smitten with one another in unreleased deleted scenes leading up to it. The kiss is interrupted by Sherman "Preacher" Dudley clearing his throat, who's still recovering from his wounds. This, of course, was part of the unreleased original ending that was changed at the last minute due to test audiences wanting Susan to die. The footage was never released but there are stills from said kiss and this was how it was scripted to end. Fans started a petition on the Change site asking Warner to release the original ending and even Thomas Jane is promoting it on his Instagram account. But as of now, the ending has yet to be released.
