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 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.

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. In the close-up of Ellen looking up at him, the boom mike bobbing around, is clearly reflected in her sunglasses. (00:41:10)
