Deep Blue Sea

Corrected entry: If the crew acknowledges the fact that these sharks have been modified enough to possibly swim backwards, why are they so shocked when it happens?

Correction: Only Dr. McCallister knew that the sharks had been genetically altered. Everyone else just thought that they were breeding them for the protein complex which would not necessarily mean that they could swim backwards.

Corrected entry: The female lead says that when her father was suffering from Alzheimer's, she had to tell him every day that his wife was dead "and watch that knowledge hit him like a train wreck". If he had no memory, why make the poor man suffer like that? Why not just tell him she was down at the shops every time he asked where she was? (00:05:10)

Correction: That is a moral dilemma. Obviously the character didn't want to lie to her father and thought it would be best if she just told him the truth. It would would also avoid further questions like "why is she taking so long down at the shops?"

Corrected entry: If these sharks were herding the people to the top of the structure to get them to flood it, why did they keep killing them off? If no one was left who would flood the building?

Correction: The sharks kept attacking to get the people moving.

Corrected entry: The sharks can break through metal, but not the glass in the oven where one of the characters is "hiding". Must be some strong glass...

Correction: Because the sharks don't have any legs, the only way they can put any real force behind a blow is to ram their target. The kitchen is so cramped that the shark can't swim around and gather any momentum, so he can't hit the oven with full force.

Corrected entry: When the female doctor strips out of her wet suit to shock the shark, she grabs the flexible metal tubing and yanks it off the wall with no problem. Two problems here. It would take more than a struggle to rip that of the wall. Second, the wires should be in "non-flexible" metal tubing. (However, I am not accustomed to electrical codes for underwater oceanic bases and perhaps the code calls for flex.) Either way, though, it would be impossible for her to simply pull the wires out without much struggle.

Correction: These are both assumptions. It is unknown how well secured the flexible tubing is to the junction box or how strong Dr. McCallister is. Remember that people in extremely intense situations can muster more strength from the adrenalin rush than they could under normal circumstances. Flexible metal tubing is an acceptable alternative to non-flexible tubing; unknown why the submitter would even think that it could not be used - especially in an oceanic base operating in international waters.

Corrected entry: Doesn't anyone watch the Weather Channel? Why was this storm a surprise to anyone? At the very least, the pilot who flew Samuel Jackson to the site would have been made aware of it before he left the airport. Also, why would a facility of this size and type not have a full-time medical provider on-site if they were going to continue to perform experiments through the weekend? Stupid from start to finish. (00:23:20 - 00:34:50)

Correction: The storm wasn't a suprise. What did the pilot care who flew Sam Jackson to the facility? That pilot was being paid by the hour for a quick turn around. The facility had sophisticated weather monitoring equipment (or at least a decent link up) as shown by many shots of the woman in the control tower who is watching the storm develop. She tells everyone in advance that there is a storm coming and they shut down the fuel pumps. The storm has no effect on the facility whatsoever, UNTIL it has been damaged by an exploding helicopter. Not stupid at all.

Corrected entry: Near the start of the movie during an underwater shot, we see a teddy bear sink like a lead weight when it would ordinarily float. (00:02:40)

Correction: It may have a weighted base so that it always sits upright.

Corrected entry: At one point in a shaft L.L. Cool J's character throws down a rope to save a few of the characters from the fast rising water. The shot shows them pull back the rope and shut the door. A few scenes later, the rope is hanging down the shaft again. (01:08:25 - 01:12:05)

Correction: It's hanging out again because they had to go back into the lab to access the generator. They put the rope back so that they could climb out of the shaft, otherwise they'd be stuck.


Correction: It shows a flash of the rope still hanging there, before they've even decided to go to the generator.

Corrected entry: In the scene where the cook is trapped by the shark, the water in the kitchen is about waist-high. When Preacher jumps out of the oven, the shark turns to get him and you see that the shark is completely underwater. Those sharks are supposed to be really big, so you should at least see the fin when it's underwater.

Correction: The water surface and the fin are offscreen in that shot, so it's impossible to say that the fin is not showing. Furthermore, in almost every other shot, the fin is shown above water.


Corrected entry: At the end of the movie, Dr. Susan McCallister cuts her hand and jumps into the water to bring the shark closer. All she had to do was stick her hand in the water so the shark could smell the blood and would come closer. Has she done this, she might have lived.

Correction: The shark is super-smart, so if it didn't see anything there to chase after, it wouldn't go after the scent of blood. Dr. McCallister knows this.

Corrected entry: At the very end of the movie, when the shark is getting out through the fence, it (the shark) backs up. Correct me if I'm wrong, but sharks can't swim backwards, no matter how much gene therapy they've had. Swimming backwards would cause water to surge into their gills, thus killing them.

Correction: Well, the characters comment earlier in the film about the super-sharks swimming backwards (when they recoil from seeing the gun), so its safe to assume that their modifications have given them the ability to do this.


Corrected entry: Carter calls Scott "Tom" twice after calling him Scott prior, when in the wet lab trying to calm him down after the rich suit gets eaten.

Correction: He never calls him "Scott", he calls him "Scoggs." The character's name is Tom Scoggins.


Corrected entry: When McCallister cuts herself and jumps into the water, you see blood in the first shot. Then when she is swimming and wading etc., there is no sign of blood at all. (01:32:25)

Correction: As soon as she jumps into the water you can see a red pool around her, that's the blood from her hand.

Corrected entry: 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? (00:51:20)

Correction: It's a massive shark, in shallow water, around tight bends for the animal. You try sprinting full pelt round a bend and you'll see why.

Corrected entry: Considering the huge size of the glass window in the facility and the fact that it is so far undersea, it must surely be several inches thick and therefore able to withstand an immense amount of pressure. Yet it breaks ridiculously easily when the shark rams the lightweight gurney into it from a considerable distance. If it was that easy to break, how come the sharks never tried it before themselves, especially as later in the movie they can knock out heavy steel doors without any effort at all?"

Correction: Firstly, I don't think the window breaks ridiculously easily. First it cracks and then big lumps of thick glass start popping out before it finally shatters. Secondly, the gurney, which is designed to be suspended from a helicopter so is probably very sturdy, is propelled at the window at great speed by the sharks who seem to have the express intention of causing the window to shatter. Thirdly, the sharks learn new tricks throughout the film. Maybe they didn't know they had the strength to break the window until they tried it. When they succeeded in breaking the window, they decided to have a go at bashing in steel doors, which seemed to take a lot of effort to break as they had no tools to do it with.

Corrected entry: In the scene where the remaining crew are climbing the maintenance shaft where the debris is falling from the elevator blocking the full way up, why doesn't the elevator itself fall? It's in a bad enough state as it is, so why does it not fall? (01:03:10)

Correction: It may have become jammed in the shaft.

Corrected entry: All winches on choppers have an emergency release in case something like the shark grabbing it happened - why didn't they use it? (00:38:30)

Correction: It was a rescue team. They would do anything to rescue Jim, and in this case things happened too fast, so the chopper was pulled without the crew being able to do anything about it. Also it would make the rescue team look bad if they just cut the wires and let Jim fall into the ocean. So I guess they stood up against a dilemma and weren't thinking straight.


Corrected entry: They are searching for batteries for this real big flashlight and finally find some in the clock. 1. How can such small batteries provide enough energy for the flashlight? 2. How do they fit in? I'd say you need bigger batteries! (01:11:00)

Correction: They don't. The batteries come from a varity of sources, the clock provides just one (maybe 2). That is why he is looking for a sex toy, for extra batteries.

Corrected entry: Anyone notice the shark could break through a steel door in 4 or 5 hits that's made to withstand tons of water pressure, but it takes 6 or 7 direct hits to get through a chainlink fence at the end and never succeeds? (01:29:30)

Correction: The door the shark is trying to batter down already has tons of water pressure behind it, the shark's added attempts were more than they were designed to withstand.

Corrected entry: Near the end of the film when LL Cool J gets bitten by the shark around his waist why doesn't he get ripped in half like all the others did when the shark first got them? (01:00:25 - 01:27:30)

Correction: If you remember when they are climbing up the maintanence ladder and carter is trying ot save Jan she gets caught by the shark around the middle but is not killed instantly.

Revealing mistake: 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 Saffron 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? (01:26:30 - 01:33:10)

Upvote valid corrections to help move entries into the corrections section.

Suggested correction: Her cheeks are like that because when we all take in a big breath of air and hold it so not to breathe, that's what happens. The hand gestures when she goes in the water is so the blood can mix with the water so the shark can smell it.

The hand gesture the entry is referring to is just before she is eaten by the shark, the actress waves her hand across her neck area, allegedly to indicate to the director that she was running out of air.

I think she is giving the shark a sign... like stop or don't attack or something like that. So I think she is giving the shark a sign because right after she does that the shark stops swimming towards her.

Maybe in the context of the film you could argue that, but for scenes in which actors are performing underwater, they use that gesture to let the director know they are running out of air.

If you look EXTREMELY closely in one shot with the girl at a close distance and the shark far away you can tell the girl is actually computer animated. So I think she is giving the shark a sign cuz right after she does that the shark stops swimming towards her. But I could be wrong... that's just what I think.

Russell Franklin: Just what the hell did you do to those sharks?
Dr. Susan McCallister: Their brains weren't large enough to harvest sufficient amounts of the protein complex. So we violated the Harvard Compact. Jim and I used gene therapies to increase their brain mass, a larger brain means more protein. As a side effect the sharks got smarter.
Janice Higgins: You stupid bitch!

Question: How did they do the scene when one of the sharks ate the bird? I know they used animatronic sharks for any interaction with the people, so did they use the same method for the bird? It was "inside" the shark after all.
