Deep Blue Sea

Factual error: Without wanting to go into extreme details, the genetics and biochemistry of the entire film is flawed. No geneticist in their right mind would even think about using gene therapy - a technique which is not entirely successful yet - to increase the size of the gland. One would use any of multiple techniques to identify and clone the gene responsible for the protein in question. It is cheaper, more successful, and a lot safer and quicker to do. A copy of the gene could be inserted into E. coli and produced on a mass scale in a beaker on land. After the protein had been isolated it would not be able to be given to patients in a pill form because it would be digested in the gut (like insulin for diabetics). (00:05:20 - 00:48:55)

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)

Continuity mistake: When Carter climbs the ladder to get out of the water after removing the licence plate from the shark's mouth, it shows a shot of his feet and he is wearing sandals. In the tank he was wearing swim fins. He talks to the big boss for a few seconds and the fins are nowhere to be seen. He then walks away with the fins in his hand. (00:08:55 - 00:10:20)

Factual error: The so-called 'tiger shark' fed to the Makos is quite unrealistic. As someone already mentioned, the snout is that of a Great White. Furthermore, the teeth are that of a Mako. Tiger shark teeth are very distinct; they resemble a cross between a dagger and a saw blade. (00:09:10)

Continuity mistake: At the start of the film when the man is trying to remove the licence plate from the sharks mouth you see a shot of him holding on to the fin on the huge shark from above the water. you can see the man is a good bit away from the mouth of the shark yet when we see the underwater shot he is just finger tips from the license plate. (00:09:20)

Continuity mistake: Look carefully at the licence plate when Blake removes it from the shark's mouth. It bends and flexes as though it's made out of rubber or even cardboard. Of course in the next scene when he throws it on the walkway, it's an ordinary licence plate. (00:09:30)

Continuity mistake: At the beginning, when Dr. McCallister is getting off the helicopter, she is wearing trousers, but when she is talking to Franklin, she is wearing a dress. (00:12:45)

Visible crew/equipment: After Preacher says "Feeding time" and the camera moves toward the window, you can see the camera's shadow down in the left corner of the screen. (00:16:55)

Mortug

Continuity mistake: When we first meet Preacher, he dips his finger into the whip cream and scoops up a good bit, but in the next shot there's considerably less on his finger. Before Preacher even offers "Bird" the whip cream off his finger, the amount of cream on his finger changes between shots. (00:17:05)

Continuity mistake: When Preacher says "Leave that to the white folks, brother," to Franklin, you can see that Preacher looks rather serious. When it cuts, Preacher is instantly smiling. (00:19:20)

Continuity mistake: When Blake and Dr Susan McAlester (Saffron Burrows) emerge to survey the damaged research facility, you can clearly see coastline in the background, although earlier in the movie we see a weather map showing the facility clearly way out in the the ocean. (00:23:25 - 01:29:20)

Visible crew/equipment: As Carter is swimming in the cage under water there is a frontal view of him where you can see the shadow of the camera moving down in the right corner of the screen. (00:24:45)

Mortug

Continuity mistake: When the shark is brought up to put the needle in his head, it bites off Jim's arm, leaving only a bit left there, but when they are wheeling him to the helicopter you see that he's got more arm than before. (00:33:50 - 00:35:25)

Revealing mistake: When the shark first attacks and bites off Jim's arm, you can see his real arm under his shirt as he's scrambling away from the water. (00:34:10)

Continuity mistake: Throughout the film, people's clothes get drier/wetter instantly. Most noticeable after Whitlock is attacked and rescued by the helicopter - everyone gets soaked but inside are dry. (00:42:20)

Ssiscool

Continuity mistake: When Preacher is talking to the Lord about his wrath, he is in a wide area of the corridor with "Sub Level 1-A" written on the wall behind him. In the next shot he is approaching the wide area with the sign again. (00:42:30)

Ssiscool

Visible crew/equipment: As Preacher and his parrot are about to go up the stairs to a higher level, you can see a wire attached to the parrot. (00:43:05)

Mortug

Visible crew/equipment: When Preacher's bird flies off, you can see the shadow of someone at the far end of the corridor on the floor. Since no-one else is around, this has to be the trainers shadow to whom the bird flies. (00:43:10)

Ssiscool

Factual error: Since the water was always waist high, how could the huge sharks swim inside? Not to mention the corridors... (00:51:10)

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!

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.
