Continuity: On the dock, Charlie and Denherder wrap a link chain around the corner piling, which is yanked when the shark takes the roast bait. In the close-up the chain is pulled taught from the front and breaks free, but in the next wide shot the chain is slack and being pulled from behind the links around the piling.

Continuity: After the first barrel pops up, Hooper and Quint gather up the rope while at the stern. The existence of rope in each of their hands changes abruptly between shots. Particularly when Quint holds the rope only in his left hand in the wide shot, but in the next dramatic close-up as it leaves a rope burn, he grips it in both hands.

Continuity: After Quint scrapes the chalkboard with his nails, in a close-up when he says, "Gonna stay alive and ante up, or gonna play it cheap," the papers pinned to the bulletin board are visible in the room behind him, as well as the chair, etc. In Quint's next close-up, the papers differ with additional pink and blue sheets and the chair is now at the other end of the board.

Continuity: After Brody walks out of the store with sign supplies, Brody places the box, etc., in Hendricks' arms, with the points of the five wood stakes facing Hendricks' right side. In the next shot, when Brody drives away as Mayor Vaughn calls out to him, Hendricks walks over with his arms full, but all the stake points now face his left.

Continuity: After buying the sign supplies, Brody drives away and as the Mayor calls out to Brody, Hendricks walks over. In the first shot certain people are walking about; however, in the next shot as Hendricks and the Mayor speak, a boy suddenly appears standing in the crosswalk, the positions of signs, etc., differ, and of course the shadows cast are entirely different.

Continuity: When the Tiger shark is displayed on the docks, the blood stains in and around the mouth and its body, either change significantly between shots or completely disappear.

Continuity: Just as Quint shouts, "You may be a big yahoo in the lab, but out here you're just supercargo..." and when he asks Brody to unbuckle him, the cleat at the stern has plenty of line wound round it and there is a red cup beside it. However, in the previous and following consecutive shots within this scene, there is no line and no cup.

Continuity: When the two old fishermen are fishing for the shark from the pier, the shark takes the bait and you can see the chain getting pulled into the sea. In the next shot you can still hear the chain being pulled into the sea but if you look on the pier, you can't see any chain being dragged in and the wooden post that the chain is secured to changes into a different position.

Visible crew/equipment: In the scene after the shark has pulled out the stern cleats and the three men are kneeling down in the boat; look at the window of the cabin door of the Orca, and you can see the crew on a separate boat being reflected in the glass.

Visible crew/equipment: When the three guys first see the shark, it shows a shot of the shark swimming past and there are shadows of equipment and about three crew members just watching the action. It's not eqiupment from the Orca because nothing is there that looks similar to this shadow.

Continuity: At his home, after Brody uncorks the bottle of wine he begins to peel the top label. In the following shots the top label changes, as well as the position of his hands, depending on camera angle as Hooper and Brody speak.

Continuity: While Brody is in the flooded cabin, before the shark joins him, in the shots facing the aft cabin wall a few things are very different. The wood paneling on the entire wall, the porthole window beside the door, the ceiling and the black fire extinguisher holder all differ, and the round fixture that was screwed into the wall is gone. Also, visible through the window, the permanent ladder is positioned differently and things hanging in front of the window differ from the previous shot.

Other: In the scene at the dinner table, when Brody's son is copying his movements, after Brody puts down his glass to cross his fingers, you see his son cross them before Brody does.

Continuity: The cleats are entirely different in many shots; they keeps changing from flat top, long, shiny silver with a wide base, to curved top, dull silver with a narrow base. When Brody unties the wrong line and when he wets the fishing reel it is the shiny flat top cleat on the transom. Yet, when he and Hooper tie off the lines the cleats are curved top. Also, the two metal plates and two metal hoods that are near the cleats repeatedly change from being very rusty, to not rusty at all.

Continuity: After the first shot of Hooper's shark dart falling, in the next shot of the shark swimming away, the cage top is wide open, yet in the previous shots and following close-up the top of the cage is closed, until Hooper actually opens it.

Continuity: The man speaking to Brody on the beach, while Brody is preoccupied with staring at the water, has salt and pepper colored hair, but in the close-up shots facing Brody the man's hair very noticeably differs, as well as his upper body structure and tan.

Continuity: The chunk of dock that floats in the water, as the shark pulls it, differs from the piece of dock that broke off in the previous shots.

Continuity: When Michael walks into the kitchen, he holds up his bloody hand and exclaims, "I got hit by a vampire!" In the next wideshot the blood on his raised palm differs.

Continuity: When the pump is given to Brody, Quint says, "Pump it out, Chief," and then Quint, with his long blue sleeves, thrusts his machete into the side of the boat. However, in the close-up Quint's arm has no sleeve whatsoever, as the machete meets the wood.

Continuity: Quint remarks, "Back home we got a taxidermy man. He gonna have a heart attack when he see what I brung him." In the shot of Orca's stern, just prior to this comment, the two attached yellow barrels are very worn, with many black marks all over. Yet, in the shot right after, both yellow barrels are almost entirely yellow - quick paint job. Throughout the Orca scenes the marks on all the barrels change many times in consecutive shots.
