Shark Zone (2003)

Factual error: Throughout the film, most of the characters talk clearly underwater with the SCUBA mouthpieces in their mouths, which is impossible.

Continuity mistake: Near the start when they are jumping out of a helicopter with scuba gear, they show one guy in an orange wetsuit with scuba gear and 1 yellow oxygen tank standing at the door about to jump, then in the next shot show a person in an all black wetsuit sitting on the edge and jumping with no scuba gear and no oxygen tank, then in the next shot where the guy is hitting the water, they show a person in a gray wetsuit with 2 red oxygen tanks.
