Revealing mistake: Just as Quint finishes scraping his nails on the chalkboard, the camera begins to move in closer when he takes the first bite of the cracker. On the right side of the screen under Harry's chin, Roy Scheider is ducking down while staring at the camera, as it pans toward Robert Shaw, and Roy then lifts his left hand up, cueing Robert's line. (00:20:55)
Continuity mistake: When Quint is up in the crow's nest, Brody tells him "Let Hooper take a turn" (regarding chumming the water). When Quint, while looking down at Brody, says "Hooper drives the boat, Chief", his right arm is across his body and looks to be resting on the safety railing of the crow's nest. When Brody looks up at Quint, his right arm is away from his body and is just holding onto the crow's nest railing with his hand.
Suggested correction: When Hooper uses the knife to pry to tooth out, it took very little effort, suggesting that the tooth wasn't wedged into that spot, but merely just resting in that spot.
The shark tooth was inserted into the wood by the prop crew with its flat root side down, which would have been impossible to have occurred during the attack on the hull. As to the statement that the tooth was "merely just resting in that spot" then Hooper would not have needed to use the blade to remove it from the wood, plus the fact that since it was underwater it would have floated away during the hours after the attack. But it did not float away, so it must have been at the very least snugly fit into the wood hull. Still impossible.

The original mistake says that the root of the tooth was embedded In the wood. Not possible since it should be the sharp end in the wood and the root showing on top (as described in the mistake).
