Corrected entry: Sea World Orlando is (obviously, since it's in Orlando) not connected to the ocean, as suggested in the movie. Therefore, there is no way that the shark could have just made its way into the park.
Corrected entry: The 'Underwater Kingdom' of Sea World Orlando is actually an attraction called Terrors of the Deep. The tunnel shown in the movie is NOT part of the actual lagoon of the marine life park, as is suggested in the movie.
Correction: Creative licence. In the film it's a new attraction to the park.
Corrected entry: The shark swallows the unfortunate British cameraman that gets trapped in the tunnel with it. Later, after breaking the Plexiglass wall, it chews up and swallows some random guy. Almost immediately afterwards, as Mike and Kay scramble around, the shark opens its mouth and we can see the body of the British cameraman, with the convenient grenade in his hand. How could the British guy's body be in the shark's mouth after it's eaten the second guy?
Correction: When the shark chewed up the guy after the British one the shark actually drops him out of its mouth leaving him floating in the water.
Corrected entry: When the shark has chased Mike and Catherine they get back into the space where they go in and out to the water. The room is completely filled with water. We see Mike's hands turning the vent-things (I don't know the proper words for them) to let the water out, only problem is his hands are not IN water. They are in air, not a drop of water in sight. Then we see the room emptying of water and Mike and Catherine are both still in water. Mike's hands should have been underwater in every shot of the scene up until then. It's obvious that the hands were Mike's as you could see his wet suit.
Correction: This is not true, at the 1:29:00 mark of the film, Mike's hand is turning a release valve to drain the water from the tank, his hand is in water, you can see by the way the light is shining on the hand and from bubbles being made by the twisting motion in the water.
Corrected entry: At the very beginning of the movie, there is a severed fish head just hanging there in the water. It is blatantly obvious that the fish is alive because the mouth is in obvious motion.
Correction: It is well known that some fish, if their head is severed from the body, can still move other parts. just like when a chicken has its head chopped off, it will still run around for a few minutes.
Correction: The Sea World Park in the film is entirely fictional and is only based on existing Sea World parks.
