Visible crew/equipment: In the scene where Brody approaches the group of teenagers on their smashed boats, the angle cuts to show Brody approaching seen as if from Cable Junction. At this point, there is a huge mistake. The teenagers' boats are clearly visible in the foreground, the kids have all completely vanished, and you can spot the cameraman standing on the boats quite clearly.
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. (01:07:15)
Visible crew/equipment: As Doug is pumping air into his boat, there is a close-up shot of the boat puncturing. If you look closely, you are able to see the explosive patch hidden where the puncture appears and the wire leading to it. (01:19:30)
Visible crew/equipment: When Brody drives across the deck and then onto the ferry, as he does you can see the large shadow of crewmembers and a camera set up, standing on a high ledge above, cast on Brody's Amity Police van. (00:03:20)
Visible crew/equipment: When the shark is coming towards Mike as his friends are trying to pull him out of the water, in the shot when the camera is on the shark's back, there is a large crew boat behind one of the sailboats, visible in the top right corner of screen. (01:22:00)
Visible crew/equipment: When Brody is rigging the winch it shows an underwater shot, presumably from the sharks point of view, if you look attached to the kids boat's there is a wire anchoring them down.
Visible crew/equipment: On the morning after Brody is fired, when his wife gets up from the kitchen table and talks to their house keeper, the shadow of a crew member holding a boom mic can be seen on the wall on the right side of screen, while the shadow of the boom mic is visible above the doorway. (01:08:20)
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. (00:50:50)
Visible crew/equipment: When Larry, Ellen Brody, and a group of others are touring some people around the beach, showing them around, they look up to see Chief Brody in the watch tower, looking out for sharks.

Visible crew/equipment: After Chief Brody rams the police boat into Cable Junction, in the behind shot, shadows of the camera and crew members are reflected on the stern of the boat below the word police. (01:40:40)
