Visible crew/equipment: While Quint tells of his experience with the U.S.S. Indianapolis, in the close-ups of Brody a crew member's arm with a watch is clearly visible moving in the reflection on the window, just behind Brody, particularly when Quint says, "Anyway, we delivered the bomb." (01:32:55)
Visible crew/equipment: As Hooper says the shark is "back for his noon feeding", you can see the camera and lighting reflected on Brody's glasses.
Visible crew/equipment: When Quint is doing his speech at the town meeting the camera slowly moves towards him. When the camera passes the man in the grey suit you can see a moving shadow near Quint. Everyone in the room is stationary in this scene apart from the cameraman and film crew. (00:20:55)
Chosen answer: As mentioned in the movie, the posion was in the needle and the shark's hide was too tough for the needle to penetrate. Hooper had to go in the water so that he could get the needle into the shark's mouth, where the flesh was less tough.
