Continuity mistake: When the parrot lands on the casserole you see a bottle and some other items floating around it. When it cuts none of the items can be seen around the casserole. (00:51:30)
Continuity mistake: Even though the shark just jumped out of the water and ate the bird, the water is still when the preacher is falling into it. A big shark should make some waves in the water. (00:51:55)
Visible crew/equipment: When Preacher falls off the shelving rack into the the water after his bird was eaten by the shark, you can clearly make out the zip for his wetsuit under his jacket. (00:52:00)
Revealing mistake: In the scene where L.L. Cool J. is in the flooded kitchen and the shark comes in through the door, he climbs up a shelf, then falls in the water, then climbs out again. Before he makes his way to the oven you can clearly see that under his pants he is wearing knee pads. (00:53:35)
Continuity mistake: When the shark is attacking the oven which the preacher is in, the shark severely damages the oven's glass door. Later, when it cuts to a shot from outside while the shark is bashing against the door, only a few cracks are visible in the glass. (00:53:40)
Continuity mistake: When Preacher is cutting through the oven, between the shots from where he is, and the view from the section of oven above him, the damage is entirely different. (00:53:50)
Continuity mistake: When LL Cool J is standing on the shelf and reaching for his bird on the pot, it is clear that he could easily reach the pot if he clenched his fingers. Yet, in the next clip, the pot is shown from a different angle and is at least 1 or 2 feet away. (00:53:55)
Factual error: A double oven has a double or triple insulating wall between ovens, not a single sheet of flimsy steel. (00:56:00)
Revealing mistake: When Samuel L. Jackson is attacked and killed by the shark, you can clearly tell that he is CGI. His arms and legs are segments and it looks really corny. (01:00:05)
Other mistake: When Carter is sitting in front of one of the small hatch-like doors around the time that they were climbing the ladder to escape from the rising water, one can clearly sea that the door is no more than twice the width of Carter (4 feet at most) yet the 45 foot shark about 10 to 12 feet wide seems to have no trouble squeezing through. (01:01:40 - 01:04:20)
Continuity mistake: Carter pries open a door with a knife that is on as sheath on his leg. The knife breaks and he throws it away. In the final scene, when Carter and Preacher are laying on the wreckage, the knife is clearly visibly back in the sheath on Carter's right leg. (01:05:00 - 01:37:45)
Continuity mistake: While Carter is trying to save Jane, he is a few feet above the water. But in a shot from above you can see that he has to bend his body so as not to touch the surface. It would be very easy for him to reach her. But in the next shot, he's high above the water again. (01:06:25)
Continuity mistake: In a scene near the end of the movie, Carter is swimming back to the wet lab through flooded passageways. At the beginning of the swim, his left shoe is completely untied - you can see both laces floating. In the next full body shot (where his shoes show) the shoe is tied again. (01:13:30)
Continuity mistake: When Carter and Scoggins are under water at the panel you can see light on Scoggins face when the camera is focusing on him. However when it cuts to Carter he is pointing his flashlight away from Scoggins. This happens twice during the shots. (01:13:45)
Continuity mistake: When Carter is swimming down to the hatch, just after the technician has been eaten, you can see that when there's a shot showing what he can see, there's a straight beam of light presumably from his torch as that's the only source it could come from. However, when the camera moves back to see Carter swimming through the water, you can see that the torch he is carrying is moving around violently as he is trying to swim to the hatch. There's no way Carter could have held that torch straight enough for it to produce such a straight beam of light, especially since he's busy trying to escape being eaten by a freakishly smart shark. (01:17:35)
Factual error: After the doctor returns to her quarters and retrieves some papers, she is trapped on a table or a desk or something and she pulls out a wire that shocks and kills the shark. Isn't it convenient that the jolt ends for some reason right when the shark dies, even though the circuit would have stayed intact and she would have been shocked upon entering the water. (01:23:10)
Continuity mistake: When Preacher, Susan and Carter realise the only way out of Aquatica is to swim and they start filling the room up with water, Preacher holds out his hands to Susan and Carter. Carter then holds his hand out flat for Susan to take, and she puts her hand on top of his. However, in the next shot Susan's hand is on top and Carter's is underneath. (01:25:25)
Revealing mistake: As soon as the three survivors are coming out of the lab through the hatch underwater, they all signal each other to rise to the top. Look at Saffron Burrows, her cheeks are full of air and you can almost see the surface above her head. You can also see the exact same shot when she is about to be eaten by the last shark. And what's with that hand gesture - to cut or for the shark to stop? (01:26:30 - 01:33:10)
Suggested correction: Her cheeks are like that because when we all take in a big breath of air and hold it so not to breathe, that's what happens. The hand gestures when she goes in the water is so the blood can mix with the water so the shark can smell it.
The hand gesture the entry is referring to is just before she is eaten by the shark, the actress waves her hand across her neck area, allegedly to indicate to the director that she was running out of air.
I think she is giving the shark a sign... like stop or don't attack or something like that. So I think she is giving the shark a sign because right after she does that the shark stops swimming towards her.
Maybe in the context of the film you could argue that, but for scenes in which actors are performing underwater, they use that gesture to let the director know they are running out of air.
If you look EXTREMELY closely in one shot with the girl at a close distance and the shark far away you can tell the girl is actually computer animated. So I think she is giving the shark a sign cuz right after she does that the shark stops swimming towards her. But I could be wrong... that's just what I think.
Continuity mistake: Near the end scene, when the three characters came to the surface, L.L. Cool J. was taken by the shark. When he was taken underwater and when he surfaced, the shark had him in her mouth on the right side. When they went under again and resurfaced, L.L.Cool J. was on the left of the shark's mouth. What? Did the shark not like him on the right side so she switched him underwater? (01:27:30)
Revealing mistake: At the end of the film, when Preacher is fighting the shark, we can see that it is a white stuntman doing the scene for LL Cool J. (01:28:00)
