Continuity: When the kid is pumping up his boat and the shark rams it, he falls into the water head first. But when he gets on board the other boat, he still has his cap on. Highly unlikely.

Continuity: After explaining what they saw when Terry's mom's boat exploded Tina asks if they can leave. Brody then puts his hand on the porch column on the left side of it. When it cuts his arm is resting on the right side of it.

Visible crew/equipment: When Brody is checking out his reflection in the small kitchen mirror, he turns around and his wife walks through the doorway into the kitchen. Above the doorway you can clearly see the whole boom mike, pole and all, which is quickly swung up out of view.

Continuity: When Brody walks out of the bathroom with a towel hanging over his left shoulder, he opens Mike’s bedroom door. Between shots the position of the towel over Brody’s shoulder changes, as you can tell by the designs on it.

Audio problem: When Chief Brody and Dr. Lureen Elkins walk along the beach, over to the huge dead whale, Brody says “I called you as soon as I heard, because I hear the bites are really big…”, his mouth does not correctly match up with the audio.

Visible crew/equipment: When Brody is at the film developer's darkroom, the developer pulls a covering over what is supposed to be a skylight. Right before the covering is fully pulled over, the "skylight" starts to dim as if it was really a stagelight.

Continuity: When Brody is out looking for the kids, and he sees Mike's boat approach - the sky in the background is overcast. When they meet, the sky is clear.

Continuity: In the close-up scenes at Cable Junction, with water, the sky is clear. But in the scene where Brody is climbing on to the cable, the sky in the background is completely gray - and actually looks like a studio wall.

Continuity: When Brody start ringing the bell he grabs on to the tower booth's poles with both hands. When it cuts, only one hand is holding on to the pole and the other hand is placed on the booth itself.

Continuity: When Brody arrives at the Grand Opening Ball he start fixing his tie and his upper shirt button goes up. When it cuts it's buttoned.

Continuity: When Tina is called forth to cut the ribbon, she walks up and stands a few feet in front of the girl in the yellow dress. When it cuts, they have moved closer to each other.

Continuity: When Tina walks to cut the ribbon, her Miss Amity sash changes position between shots.

Revealing: In the overhead shot, when the shark is going under the "Tina's Joy" boat, you can see the shark is being driven by a propeller as the water behind it foams.

Continuity: When Dr. Lureen Elkins is walking around the dead whale you can see a man in a black t-shirt in the background covering his nose with his hand and then lowering his hand. When it cuts to a close-up of Elkins and Brody, the man is still covering his nose.

Continuity: When Eddie gets the blanket out of the wooden box for Tina, there is a large board of wood sticking out of the wooden box. In the next overhead shot it has vanished.

Continuity: When Mike and all of his friends are at the bar, Mike has a glass of coke on top of a napkin, sitting in front of him. However in one shot of Mike saying “yeah, sure,” the coke has vanished. Through the same bar scene items on the bar change their positions, move around, appear, etc,.

Continuity: When Brody is in his office, he pours a coffee. Then in one shot you can see the mug on top of the filing cabinet, and the phone rings and Brody walks over and answers it - both hands empty. Yet when he puts the phone down, he picks up the coffee mug from off of the desk, next to the telephone…

Factual error: Whenever we see the shark gliding through the water, we only see the dorsal fin, never the tail fin. Realistically, we should see both fins above the water in at least some shots - especially when the dorsal fin is fully out of the water.

Continuity: After Tina and Eddie have discovered the dead whale on the beach, it fades to an overhead shot of the beach. On the shore there are three sailing boats, one with a white sail, one with a light blue sail, and the other with a dark green sail. Nothing else. Yet in the next close-up of Chief Brody and Dr. Lureen Elkins walking along the beach, an inflatable raft has now appeared on the beach, next to the boat with the dark green sail.

Continuity: When Terry is water-skiing, the sky keeps alternating from cloudy to sunny and back, and the roughness of the waters she skies on changes as well.
