Continuity: When Vivo finds Pantucci snooping around the cargo, he throws him to the middle of the mercenaries, and they all get around him, including T. Ray who smiles at him; when T. Ray smiles at Joey he is standing up, but when he gives the first kick he is sitting down. (Time)

Revealing: Occasionally, when the characters are being eaten by the sea-monsters, you can see pieces of the computer-generated beasts going "through" the victim.

Revealing: When one of the bad guys is being dragged around by the monsters and thrown against pipes and walls and such, in wide shots you can see there is no monster really pulling him, and from the stiffness and position of his body, he is likely on some sort of device to swing him around.

Continuity: When the guy and the girl (the stars of the movie) are jumping out of the big boat, you can clearly see that when they land in the water they are going to fall off and they cut it so that it looks like they landed great.
