Deep Blue Sea

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)

Other mistake: After Scoggins is eaten by the shark underwater in the wet lab, Carter quickly goes up to get some air with his face in between two pipes. When he submerges again to swim down to the hatch to escape, the water is perfectly clear; after an attack so close the water would be cloudy with blood and bits of human skin and worse.

Other mistake: Near the beginning of the film, Carter asks Tom how high the fences are, then he tells them to make them higher, and Scoggs confirmed they were raised, but you can see that the fences never get any higher.

Mistakes

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.

Yes, Saffron Burrows' character, Dr. Susan McAlester, used the hand gesture to lure the shark by mixing her blood in the water, rather than signalling that she was out of air. While she was holding her breath with puffy cheeks, this action demonstrated her intelligence and scientific understanding of shark behaviour. Her strategy aimed to draw the shark closer, allowing her colleagues a chance to kill it, even though it ultimately led to her tragic fate of being eaten.

Saffron Burrows' puffy-cheeked face is proof that both scenes were filmed in a real underwater environment and Burrows performed her own stunts underwater by holding her breath.

Quotes

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!

Questions

Question: How did they do the scene when one of the sharks ate the bird? I know they used animatronic sharks for any interaction with the people, so did they use the same method for the bird? It was "inside" the shark after all.

Answer: This was a CGI scene.
