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)
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: 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.
Corrected entry: Those big sharks can tow a helicopter and yet in the opening scene, when Carter catches this shark, the shark is not able to tow the boat, which the harpoon is towed to.
Correction: He shot that shark twice with a tranquilliser. So it was heavily sedated.
Corrected entry: When Preach gets into the oven the water level is at the middle of the window. The level would be the same inside, it's not air tight.
Correction: Usually in an underwater environment (such as a submarine) it would be airtight to prevent spread of fires and the using up of oxygen. This could well be the same for the underwater labs.
Corrected entry: Am I the only one bothered by Preacher getting bitten so badly he nearly passes out from the broken leg, yet when he is either shooting at the shark and Carter, or setting the wires, he stands easily on his injured leg? At first the leg seems to inhibit him, but it must magically heal as the movie continues. (01:28:55 - 01:34:05)
Correction: It's possible that he was only bitten badly - it never says that his leg is broken. Also, if it was, he could have been balancing on his unbitten leg.
Correction: He didn't "nearly pass out" from his injured leg; he was probably just taking a nap at the end as evidenced by him opening one eye. Plus, I'm sure he was still in a lot pain as every time we see him crawl/move around, he's wincing/grunting.
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.
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: 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: Towards the end of the movie, just before Saffron Burrows' character is eaten by the shark, she makes a slashing motion across her throat. This is the underwater signal for, "I'm out of air."
Correction: This has already been submitted. It wont let me delete based on duplicate entry but it's entry 142121.
Corrected entry: Near the end of the movie when the three are preparing to exit the sinking building and float to the surface the comment is made that putting the life jackets on will cause them to float to the surface too quickly and their lungs would pop. When you watch them swim to the top, they actually swim faster than the jackets/fire extinguishers go. (01:24:30 - 01:26:50)
Correction: The fire extinguishers and life jackets were rotating and because the fire extinguishers were going off, they would not go straight up. The force from the fire extinguishers would push the jackets down or at least slow them down when it was pointed upward, and since it was rotating it would most likely go up as slow as it did.
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.
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.
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.
Corrected entry: Carter doesn't have any tracker device or any other to find the lost shark in the open sea, so it would be impossible to find him.
Correction: There was no need to look for the shark because the shark was looking for them, as its intelligence was vastly increased.
Correction: The shark was not looking for Carter - it's established that the sharks are very intelligent but they are still animals.
Corrected entry: Several times, the sharks swim backwards to move down a different hallway or change direction. This is an impossible feat for sharks, regardless of their intelligence.
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: After Carter sedates the shark at aquatica, he could not be able to carry him by himself to the lab.
Correction: The force of the shark exploding blew him around underwater.
