Continuity mistake: When the shark slams into the cage and makes Hooper drop his weapon, it shows the underside of the shark; look at the its mouth.

Continuity mistake: At the hospital, where Larry waits for Brody to approach, Larry quickly moves his left hand away from the front desk between frames. (01:04:50)
Continuity mistake: Before Alex Kintner is attacked, Sean Brody is shown sitting on the beach singing. After Alex is attacked and people are running out of the water, Sean can be seen standing on the beach, and in one shot, Chief Brody can be seen grabbing him. But a couple of seconds later, Sean is shown sitting on the beach in the same spot he was before, as if he hadn't moved. (00:16:55)
Continuity mistake: When Hooper first gets introduced in the movie on the pier, greeted by a fisherman, you notice in the background a man going down a ladder. Only for the camera to cut back to Hooper with the same man going down the same ladder again.

Continuity mistake: When all 3 men are putting the shark cage together for Hooper, and they move the cage over to the side of the boat, Brody is shirtless. Then the next shot where the cage is going into the water, Brody's black T-shirt is back on.
Continuity mistake: When Jaws leaves the pond after the attack its fins go below the water as it approaches the bridge, the scene immediately changes to the bridge, the woman is shouting "shark" and we see the fins go below the water again.
Continuity mistake: When the man gets attacked the long shot shows two of the three boys on top of the upturned boat, then we see the leg sink to the bottom with a trainer on, even though the man was bare footed. Then the camera passes the boy in the water and the other two boys are only just climbing up onto the boat.
Continuity mistake: When the Kitner boy was attacked, the underwater shots show the swimmers treading water in fairly deep water, but the above shots show the kids standing in shallow water.
Continuity mistake: When Brody is on the mast of the Orca with Quint's rifle, preparing to shoot the shark, the shark emerges from the water and there is blood on the end of its nose, but after a quick cut to Brody, we return to the shark and blood has disappeared. (01:59:20)
Continuity mistake: When the shark is attacking Hooper in the cage, what happened to the the lines to the barrels they have shot into the shark?
Answer: Although the 1995 documentary "The Making of Jaws" claims that the shooting star was real, the fact is that the shooting-star background effect is a Steven Spielberg trademark in most of his films (first noticed in "Jaws," but also appearing in "Close Encounters," "E.T. The Extraterrestrial," "Indiana Jones and the Temple of Doom," "Saving Private Ryan" and others). Spielberg has always had a fascination with shooting stars, dating back to his childhood, and he works them into almost every film.
