Continuity: When Hooper runs below deck to get the homing device, life jackets hang on top of the rope, to the left of the machete. When Quint gets the machete there are no life jackets near it and when the engine hatch blows up, life jackets hang against the wall where the machete was. The life jackets near the fire extinguishers change position as well.

Continuity: In the council chambers, after the Mayor says, "Only 24 hrs," as the people argue in the wideshot a particular area of the chalkboard is visible behind them and it is blank. In the very next close-up Quint, who was not in the previous shot, scrapes the board with his nails, which now shows the large doodle of the shark, that should have also been visible in the previous shot, but was not.

Continuity: As Orca heads out, first there is an interior shot that pans in through the large shark jaw framed window, showing the Orca a good distance away from Quint's place. However, in the next close-up of Brody, the Orca is just pulling away from shore.

Continuity: When Chrissie goes swimming at the start of the film, we see the moon in the distance. However, when we see Chrissie from the shark's point of view under the water, the moon is directly above Chrissie.

Visible crew/equipment: In the scene where Quint shoots the shark with a harpoon gun, when the harpoon hits the shark you can see the shadow of the cameraman.

Continuity: After the cleats are ripped off, the size, shape and characteristics of the exposed area of wood underneath significantly changes in some of the following shots.

Continuity: When Sean mimics his father, Brody's glasses are lying upright on the table. However, when Hooper sits down the glasses are upside down and other things on the table change position, etc.

Continuity: When Brody waits to board the ferry he says, "Charlie, take me over to those kids, will ya," and on the base of the ferry 'Amity' is written in large, bold, black letters. However, when they reach the other ferry landing the word 'Amity' is gone. It is the same side of the ferry, note the ferry driver and the back end of the car.

Continuity: As the shark bursts through the port side windows, the remaining port side wall and window frame around it keeps changing between shots - from an entirely broken frame to a partial intact frame, and so forth.

Continuity: When Brody is in the flooded cabin as it tips, at the start of the shot where the shark makes its smashing entrance, we actually hear Brody's loud footsteps on wood, as we see his waist and legs run from aft to forward in the cabin; though in the previous shots Brody is more than waist level in the water, already standing towards the bow.

Continuity: Throughout the film, there are abrupt changes concerning the position of the sun's shadow, or going from being windy to not, or being overcast to bright and sunny, or where the water is either at a dead calm or pretty rough, all between consecutive shots within a scene.

Visible crew/equipment: Throughout the film, reflector screens, spots, etc., are reflected in various characters' eyeglasses and sunglasses.

Visible crew/equipment: While the shark's face is up close and personal in the cage with Hooper, the equipment under the shark is visible as the camera pans back and is visible again in following shots. In the shot just prior to Hooper swimming away the device is quite clear.

Continuity: When the fishing reel clicks, Quint readies himself in his chair and Brody is finally successful with the knot. The knot in the rope, and the way he holds it, differs between the close-up and wideshot.

Continuity: When the shark swims away with the roast bait, a dramatic close-up of the quickly unfurling thick link chain lying on the dock is shown beside the trashcan. The unmoving end of the chain lies behind, to the left of the trashcan and the end being pulled is on the right, with the slack at the center. Now when the chain is pulled taught in the following shots, the trashcan should have flipped over, if the slack chain was indeed where it was shown to be in the close-up. In the wide shots the trashcan sits on the left at the center of the dock, but the chain being pulled is attached to the piling at the right corner end of the dock.

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: In his bedroom, when Chief Brody asks, "How come the sun didn't used to shine in here?" the ashtray and lamp are visible beside Ellen. In the following shots the ashtray and lamp's electrical cord noticeably keep changing positions. When he walks out of the bedroom, something (mug?) appears on the desk near the window that wasn't there in the previous shot.

Continuity: When Hooper runs below deck to get the electronic homing device, in the wideshot he breaks apart the plastic case, throwing the clear top to one side and the yellow bottom to the other side. However in the next close-up the plastic case is suddenly intact, right below Hooper's hands. The yellow cord is in Hooper's hand in the wideshots, but not in the close-up.

Continuity: While Hooper and Brody speak with Quint at his place, Quint tosses a large duffel at Hooper. In the shot looking up, the opening of the bag faces Quint, when it is inches away from Hooper's hands. However, in the next overhead shot as Hooper catches it, the duffel now faces the opposite direction.

Continuity: At Quint's, when he holds the two steaming shark jaws, assorted dry goods on the shelves above the stove are seen, particularly the cans of Del Monte vegetables. When Quint gives Hooper the rope to tie the knot, some of the goods on the bottom shelf and every can of veggies on the top shelf are entirely different.
