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.


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.


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: When the female doctor gets off the table after electrocuting the shark, she left the wires in the water, therefore when she got off the table she would have been electrocuted through the water too.

Correction: Electrocuting the shark would have shorted out the wires, hence there'd be no more electricity flow.

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: 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: 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.


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: 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: 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: 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.

Correction: Trying to point out factual errors in a film like this is like saying its impossible for Dinosaurs to exist in "Jurrasic Park". Its commented in the film by the characters that they shouldn't be able to do that and yet somehow they have been able to.

Corrected entry: After Carter sedates the shark at aquatica, he could not be able to carry him by himself to the lab.


Correction: There is no time scale on the time between the shark being sedated and it arriving in the lab.

Factual error: Near the beginning when the boat pulls up and the guy on the boat tells the blond convict he's got a beauty 13 foot "Tiger shark" that's up in some sort of sling, the so called tiger shark is actually the same robot mako shark from the rest of the movie, just with stripes on it. Tiger sharks have a blunt rounded nose, not a pointed one like a great white. (00:07:35)

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: Director Renny Harlin has a cameo as one of the employees of Aquatica who are leaving the facility for their weekend break in the opening scene.

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.
