Revealing mistake: When Nick has swam back to his water scooter, he climbs up and drives away and the shark comes up behind him. But look carefully behind Nick as he is climbing. The nose of the shark is visible during the whole scene, right under the surface. This proves that the shark was a dummy, waiting to come up.
Revealing mistake: In the first morgue scene the body on the table is obviously breathing.

Continuity mistake: In the scene where Miter is planning to escape from the army and Bozz tries to stop him, watch the red mark on Miter's neck. It miraculously disappears and reappears many times. (00:45:05 - 00:48:30)
Plot hole: When Captain Towers gives his XO an injection to allow him to die in peace, he, properly, swabs the site with alcohol, and slips the needle into the vein. However, immediately below the injection site, is a hep-lock.a port installed into a vein to allow injectables to be administered. I cannot imagine that a senior Naval officer would be so ignorant of the port's function.
Other mistake: In the scene where hundreds of men burst into the place where Penelope Cruz gives her cooking lessons, you can see that one of the waitresses drops the plate she is holding a split-second before the guys swing the doors open and rush past her.
Continuity mistake: In the last scene to be filmed, with Orlock and Gretta, the candles on the dresser are alternately lit and then out, as Orlock's reflection is visible then not in the mirror.
