A businessman sinks $200 million into a special project to help fight Alzheimer's disease. As part of this project, medical biologist Susan McAlester rather naughtily figures out a way to genetically enlarge shark brains, so that disease-battling enzymes can be harvested. However, the shark subjects become super smart and decide they don't much like being cooped up in pens and being stabbed with hypodermics, so they figure a way to break out and make for the open sea...

Did You Know?


Three of the main cast members are reunited through the Marvel Cinematic Universe films and television shows: Samuel L. Jackson starred as Nick Fury in several Marvel films such as The Avengers (2012), which also starred Stellan Skarsgård as Dr. Selvig. Saffron Burrows starred in the spin-off television series Agents of S.H.I.E.L.D. (2013) as Victoria Hand. Additionally, Thomas Jane played the Marvel character The Punisher in The Punisher (2004), but that film is not part of the Marvel Cinematic Universe. See more »


During the Climax of the movie, the survivors make an improvised explosive using the black powder from 10 flares. One of the characters mentions that they could get 2 1/2 sticks of dynamite form the flares. In truth the flares they're using each contain only about 1.5 grams of black powder. They would need 450 of those flares to get the equivalent of 2 1/2 sticks of dynamite. See more »


Preacher: You're the guy that got caught in that avalanche, right?
Russell Franklin: Yeah, I'm the one.
Preacher: Like black men don't have enough ways to get killed without climbing up some stupid ass mountain in the middle of God's nowhere! You leave that to the white folks! Brother!

Alternate Versions

SPOILER:In a test screening one month before the film's opening, the ending had Susan () escaping the shark at the end and saving the day with the spear gun. Audiences booed that ending, and sure enough, it came out with Susan getting eaten and Preacher () saving the day. You can actually tell that some of the final shots were three-shots, with empty space where Burrows would have been. Sometimes 's eye-line looks like it should go to her. She's been digitally erased.

One of my favorite shark horror monsters movies and favorite Thomas Jane film
8 December 2017 | by ivo-cobra8See all my reviews

Deep Blue Sea (1999) is my favorite shark monsters horror film and favorite film of Thomas Jane. I am a fan of the actor and this one The Punisher (2004) and Thursday (1998) are his favorite roles. Carter Blake is my favorite Thomas Jane role he played. It is my childhood movie I saw it as a kid, I never had a problems with the film. It is fast paced, entertaining action horror flick. The idea about Alzheimer's disease making sharks smart was brilliant.

I enjoy this film it is my favorite shark film, a lot of peoples are going for Jaws this is my favorite monster shark movie. From the actors, the plot, the story, music score, stunts and real practical effects no stupid CGI, I love movies like that. I love this film to death I love it so damn much. If you like Jurassic Park (1993) then you will like this one, this is another film with animals who become smart. A preview tour, a theme park suffers a major power breakdown that allows its cloned dinosaur exhibits to run amok.

In Jurassic Park was breakdown and a paleontologist with two kids in the park has to fight for survival, but in this movie a team of scientist must fight for survival when trio biogenic sharks becomes smarter and they flood the facility now the team must come on surfers and fight for survival.

Searching for a cure to Alzheimer's disease, a group of scientists on an isolated research facility become the prey, as a trio of intelligent sharks fight back. The situation plunges into chaos when multiple genetically engineered sharks go on rampage and flood the facility.

I love this film and it really surprised me with the plot twist:

LL Cool J as Sherman "Preacher" Dudley so surprised me when he was stuck in the accident in the kitchen he dealt with the shark him self who eat his bird.Jumps out of upper oven and swims away, "You ate my bird!" lights lighter, throws lighter into open oven and blows up the shark fantastic scene.

Thomas Jane as Carter Blake was the most smartest, tougher guy, brave shark hunter I have ever seen. He saved those people in the water in the opening scene from shark in which a shark wanted to eat them. I love his character he fought against the third shark and he kicked his ass. He was a brave hero I love the actor so damn much. He gave a good performance of him self. He wrestler the shark in which preacher shot's him with a harpoon and blows up the shark, but my hero survives I love that so much. Thomas Jane is a great actor I love him in this movie.

Saffron Burrows as Dr. Susan McAlester anti heroine and the tritagonist the head of a team of scientists was excellent as the villain the same time was also a heroine in this film. I love the actress so much. Wonder what happened to her?, I don't see her in any good movies this days since she went making this movie "Deep Blue Sea". Saffron Burrows was great as Dr. Susan McAlester she electrocute the second shark with a power cable all by her self that was a bad-ass scene. She sacrifice her self by helping Carter stopping the third shark from escaping.

This film was directed by Finnish director Renny Harlin who previous directed A Nightmare on Elm Street 4: The Dream Master, Cliffhanger, Die Hard 2, The Long Kiss Goodnight and Mindhunters which I thought he did a great job directing it. Music score for this film was excellent by Trevor Rabin.

Jurassic World (2015) copied Deep Blue Sea (1999) T-Rex was faster and smarter hunter and he tricked people believing he escaped off the fence, but actually he was hunting them, they make, the T-Rex smarter hunter! I already saw that in Deep Blue Sea, when doctors implant the human brains in the sharks. In here they did the same thing with the T-Rex!

This movie come out the same year as The Matrix come out and of course I went to see that movie in the movie theater with my mom. This movie I ranted in the video store a year later on VHS tape.

Samuel L. Jackson is in here and he surprised he was eaten again the same he was eaten in Jurassic Park. I thought Samuel L. Jackson will be the lead guy, but I was surprised when he was eaten by a shark.

Stellan Skarsgård is in this movie from Thor and Thor: The Dark World and he is so young and thin in this movie.

You have adrenaline-pumped shock waves and of course you have a great explosion, great underwater scenes. Thomas Jane did 100% of him in this movie. Everything was for real no CGI bulls***.

10/10 I love this flick to death, it is my all time favorite shark monster horror film. You love Jaws I love Deep Blue Sea to death! Especially I love the ending and the conclusion only two heroes survives in this movie.

I love the song Deepest Bluest (Shark's Fin) that was performed from LL Cool J. for this movie.
