Corrected entry: At the point when the Orca breaks down, Roy Scheider, Richard Dreyfuss and Robert Shaw are stuck out in the ocean with the Shark, Robert Shaw goes back into the boat to get some life jackets, as he comes out he throws the life jackets to the others. If you turn up the sound very loudly at this point you can hear Robert Shaw fart. You can only hear it if you turn up the volume, Robert Shaw then walks off the edge of the boat with a smirk on his face, he shouldn't be doing this when it is clearly now do or die for the three of them.
Corrected entry: When the shark was dragging Chrissie in the water, why didn't it just pull her underwater as soon as it grabbed her? I thought the shark didn't want to wait to eat his meal.
Corrected entry: When Chief Brody is attempting to pump the water out of the boat, he has the drain hose of the pump lying on the deck right next to him. So, in essence, he was doing absolutely no good whatsoever.
Corrected entry: Another scene that is proof that the film was made in either early spring or late fall is the scene where the mayor is arguing with Hooper and Brody about the existence of a shark in front of the graffiti covered sign. It is supposed to be right before July 4th, yet everyone is in coats and jackets.
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: At the end of the movie when the shark explodes and we see it sinking to the bottom of the ocean, the ropes connecting the dorsal and the tail fins are visible (broken). You can see the same thing in the shot where the shark jumps up onto the Orca.
Corrected entry: In the scene where Bruce (the Shark) rams the cage, you can see Hooper with blood coming from a small wound (it is his, I've checked). after a bit of this he swims to the bottom of the ocean. His wound may have stopped bleeding, but couldn't have healed so fast and the shark would have caught his blood trail instantly.
Corrected entry: In the scene where the guys are sitting on the boat, singing "Show me the way to go home" when one of the guys (can't remember who) shushes the other two. The camera goes to a board where the shark is about to hit. The board is already cracked before the shark hits it.
Corrected entry: Richard Dreyfus is driving the boat, then playing cards, then driving again.
Corrected entry: When the little boy on the yellow water raft is supposedly eaten by Jaws, you see two boys carrying him out of the water when everyone is clearing out.
Corrected entry: On the report Chief Brody is typing up while talking to the coroner, the girl's body is listed as being found late at night. It was during the day.
Corrected entry: Throughout the film, most notably in the scenes where Dreyfuss is attacked in the cage and the Orca is repeatedly rammed by the shark, the action depends upon the shark swimming backwards. No shark can do this.
Corrected entry: In the scene where Brody is stabbing the shark with the harpoon, he is stabbing the shark's head. But when the shark goes underwater, it shows the harpoon being stuck in his mouth. (01:59:38)
Corrected entry: Chief Brody is at the wheel of the boat and Hooper and Quint are trying to fix the engine. Brody can only turn the wheel (in his words) about 3 inches. Just then some of the yellow barrels surface and they stop what they're doing to start the boat to chase the shark. The boat steers fine.
