Revealing mistake: During the sequence when Michael has his underwater motorcraft and the shark attacks him, you can see in certain long shots the machine which works the shark protruding from under its tail.
Continuity mistake: When Mike sees through the binoculars that his mom is walking with hoagie sandwich, you can see she is wearing white shoes. However, when it cuts to the next shot she is barefoot.
Continuity mistake: In one of the final scenes in which the shark is attacking, the colour of the water is not consistent in the background. In one scene it is light blue, and in the other it is much darker blue.
Continuity mistake: The transmitter device that Jake attaches to the shark is missing between shots during the entire movie.
Continuity mistake: When Ellen is on the boat, and sees the shark coming towards her, the distance between her and the shark does not look very far. When it cuts to Mike, Jake and Hogie in the plane, from their view the distance between the boat and shark looks much greater, about 60-70 metres. Also, only about five seconds later, the shark jumps out of the water and strikes the boat, the shark could not have swam that distance in such a short time.
Revealing mistake: When Jake falls into the water by accident and lands in the sharks mouth, you can see a pole attached to the side of the shark used to turn the shark and the body side to side.
Plot hole: Why does the shark EXPLODE when it gets stabbed by the boat in the end? It had a transmitter of electromagnetic energy designed to shock it rammed down its throat, nothing that would explode like that.
Character mistake: When Polly answers the phone and is told of the log drifting in the channel, she immediately yells to Sean and tells him this. However, she does not leave enough time for the caller to be able to tell her all this, she leaves 1-2 seconds before passing it on to Sean.
Revealing mistake: In the scene where the shark has Michael cornered in the old, rusted boat; as he's about to use his oxygen tank to rocket up to the surface, the shark breaks through the wall and when it does, a large number of thick tubes can be seen running into the shark to make it work.
Revealing mistake: When the shark is rammed by the boat at the end, right before it explodes it is too obvious that the shark is a model. Some signs are: the oversized dorsal fins, its mouth is bent at an unrealistic angle, and it doesn't have eyes.
Factual error: The shark that attacks the Brodys in the Bahamas is presumably the same one that kills poor Sean Brody on Amity Island (that poor kid can't catch a break). Ellen departs for the Bahamas after Sean's funeral and the shark follows shortly thereafter. So, the shark swims from Amity, an island off the North Atlantic Coast, down to the Bahamas in order to stalk Ellen, Mike, etc. in a matter of days. Hmmm. As Matt Hooper said in the first film, "fast fish".
Continuity mistake: When Jake and the crew struggle against the shark, all the shots where Hoagie's body is in the back have no continuity with his position in the next shot of him.
Continuity mistake: When Jake is about to be eaten his shirt swaps from dark pink to light pink between shots.
Revealing mistake: When the shark explodes, in the last shot (from behind the boat) which shows him exploding it is painfully obvious that the boat is only a model and not the real boat from previous shots.
Suggested correction: No, it's the pole Jake attached the electro magnetic device to.
Mortug
No, it's not. This pole looks different than one Jake attached the electromagnetic device to.
