Deep Blue Sea

Corrected entry: Didn't anyone think it strange that after initial shark attack that no one of the group wonders where Preach is or mentions him, yet they don't seem a bit surprised when he saves them all? (01:08:05)

Correction: Actually, when they hear noises at one point earlier in the film, they call out "Preach?", so they know he might be around, but they probably assume he's dead - if the second floor was flooded they would assume the third floor was too.

Shay

Corrected entry: How did the sharks know that they could "sink" Aquatica? It was already underwater. Were they genetically enhanced and provided with blueprints on how to do this? The whole concept is flawed. Despite having enhanced intelligence, they would still have to learn that CCTV cameras transmit images to the cast. They could never know that wounding someone would bring a helicopter they could use to sink the structure. The whole concept of the film is based on the, frankly, wrong assumption that being more intelligent makes a creature automatically 'know' more stuff. Well it doesn't. It would just make them more able to learn and understand. So who taught them?

Correction: It's entirely possible that the sharks just got lucky. They could work out from seeing the blond guy making signals into the CCTV cameras that there was someone watching at the other end, they got very lucky with the helicopter (it was pure chance that the stretcher broke and dropped into the water) so it's possible that attacking Jim was just malicious and only when the stretcher fell into the water did the rest of the plan fall into place. It doesn't take any great amount of knowledge to realise that filling things with water sinks them. The mistake presumes that the sharks had every move planned - as the female scientist says, they're still just animals. Most of the events in the film are pure bad luck.

Shay

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: Sharks don't make any sounds.

Correction: Actually, shark attack victims have been documented as saying that right before they were attacked, they heard a roaring sound, similar to a lion.

Corrected entry: In the beginning when the blonde-haired ex convict was in the tunnel surveying the sharks, the sharks co-ordinated an attack in which they both hit the tunnel in the same second. How could they have done this? Becoming smarter does not give them the ability to communicate.

Correction: No, but being smarter might allow one to observe the other's preparation to attack, predict the attack, and work in tandem in order to secure a piece of the kill. Intelligence advanced enough would allow them to follow a predictive logical process and act on their conclusions.

Phoenix

Corrected entry: The sharks cut the electricity for the lights when they were trying to catch Carter. However, when the helicopter comes Brenda is using a spotlight.

Correction: They probably could only attack the circuit to the underwater lights; in the surface shots when Whitlock is being loaded into the helicopter, lights are visible around the perimeter.

Phoenix

Corrected entry: Just before the two sharks simultaneously attack Carter while he is diving through the underwater cage-like corridor with his harpoon we see the rest of the crew monitoring this with the help of tree monitors displaying the pictures of the underwater cameras in the cages (later destroyed by the sharks). The view on the left screen is taken from a camera that keeps moving backwards while Carter swimming towards it. This displayed shot can't be taken by one of the fixed observation cameras.

Correction: The camera isn't moving backwards, the tech is switching the feed from one camera to another farther down.

Phoenix

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.

furious1116

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

Corrected entry: Towards the end of the film when Carter is being dragged along by the shark, the shark rams into a wire fence. You can see that half of Carter is dragged through the hole in the fence. When you see the underwater shot of the shark exploding, Carter is to the left of the whole and is within the compound. When Preach calls out to him, he is outside the compund. How did he move so fast? (01:35:40)

Correction: The force of the shark exploding blew him around underwater.

furious1116

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.

Phoenix

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: 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: In the scene where the head scientist takes her wetsuit off to electrocute the shark, her wetsuit is soaking wet so it would make no difference if it was made of rubber or not, she should have been shocked as well.

Correction: Actually, I thought this too, but there was a program on the BBC in the UK about 2 months ago that proved this piece of 'movie science' would actually work.

Corrected entry: Mako sharks can't get that long.

Correction: It is stated in the movie that the scientists used genetic manipulation to make the makos grow a lot bigger.

Corrected entry: For the entire wet lab scene, the Mako shark is half-submerged in the pool. We are to assume that sharks only need to be in water to survive. However, sharks must also keep swimming in order to get oxygen-rich water into their gills. Without this, they would drown or suffocate. Certain species, such as the Nurse shark or the Australian Wobbegong, have adapted to remain motionless on the ocean floor for hours at a time. But an oceanic species like the Mako would have died in the wet lab's conditions.

Correction: You can see that during the wet lab scene, they keep a rush of water flowing past the shark's gills, so that it wouldn't suffocate.

Corrected entry: Toward the end, as people are fleeing the coastline, we see a group of refugees watching a television on a truck alongside the road. They are watching MSNBC. Must have a pretty long cable.

Correction: You can mount one of the newer small satellite dishes on a vehicle if you have a power source and a compass to align it. It's a bit odd to flee a hurricane and take your tv and satellite dish, but it's certainly possible.

Grumpy Scot

Corrected entry: If these sharks are strong enough to open metal watertight doors, how come they couldn't break through the fencing without sinking the place.

Correction: The lower part of the fence is titanium. The whole point of the movie is that the mega-sharks are intelligent enough to sink the facility so they can break through the top part of the fence, made of steel.

Jez

Corrected entry: Sharks are attracted to the smell of blood not the sight of it or something that looks like it. So in the opening scene when the wine is knocked over into the water it shouldn't be a big deal.

Correction: The shark is attacking the boat before the wine spills over (in fact it causes the bottle to topple), it doesn't think that the wine is blood. This shot is really just for effect.

Jez

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.

Jez

Revealing mistake: 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. (00:34:10)

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!

Trivia: In both Jaws and Deep Blue Sea there is a scene involving a license plate. In Jaws it is removed from the belly of the dead tiger shark. In Deep Blue Sea it is removed from the teeth of a tiger shark. Not only are both sharks the same but both plates are from Louisiana. The license plate number is the same in both films: 007 o 981 Exp 72-73.
