Corrected entry: Hooper says he can't poison Bruce because his skin is too thick and he'll have to go in the water and poke him in the mouth. However, when Brody stabs him in the head with the gaff, it leaves several bloody holes. It's just a bit too convenient for the plot to be believable that Hooper would choose to go into the water with a creature so powerful and dangerous (as opposed to at least trying to drug him from the surface first). And he had enough of the drug to try more than once: he fills one syringe from a good sized bottle of the stuff.Grumpy Scot
Corrected entry: Chief Brody and Hooper go to the wharf to dissect a large tiger shark and examine the contents of its stomach. Finding nothing unusual, Hooper recommends they go offshore that night to search for the real killer shark because "he's a night feeder." Coming from a marine biologist, that remark really makes no sense. Hooper knew that, in addition to eating Chrissie the midnight swimmer, the shark also ate Pippin (the black Labrador retriever) and the Kintner boy in the middle of the day at a public beach. Based on all available evidence, the shark was no more likely to feed at night than in broad daylight.Charles Austin Miller
Corrected entry: After Hooper cuts open the Tiger shark, he tells Brody that it isn't the shark. He adds "you still got a hell of a fish out there, with a mouth about this big." He indicates size of the bite by holding his hands about 2 feet apart. This estimate is based on the bite marks on the first victim. Of course, later we see the shark's bite radius is much larger, around 3 to 4 feet. Hooper is a shark expert and should be able to more accurately determine bite radius. (00:44:30)djm
Corrected entry: When Brody fills out the report on the girl found on the beach he has an orange towel on his right shoulder. It is still there under his jacket when he walks down the road. When it switches to the front shot it's gone.
Corrected entry: In the whole movie, the shark eats five people, including Quint, and what appears to be at least half a refrigerator full of meat. If a shark did this in real life, no matter how big it was, it would die from gorging itself, since sharks are cold-blooded and, like snakes and lizards, can take up to six months digesting a meal.
Corrected entry: In the scene towards the end of the film, when they are trying to outrun the shark back to land (when Quint says something like: we'll get him in the shallows and drown him) you see a shot from the rear of the boat, and in the distance you can clearly see the shore line. But after that point in the movie, you never see the shore, even when they are swimming back at the very end.
