Continuity mistake: During the capsizing in the disco, a light rigging falls and knocks some people over. There is a woman in a black top and pink skirt - she falls over twice between the two shots.
Continuity mistake: When the survivors are climbing out through the propeller tube, Dylan is the first one out with the others following him. But after everyone is out he is the last out to climb out.
Suggested correction: It's very obvious that Dylan is not getting out, but merely looks inside the hole, and is then standing up, so he was there all the time after he got out first, and then just looked into the hole, after everyone got in the tube, then gets up.
Continuity mistake: During the capsize, when the woman falls from above the elevator to her death, she is flipping a different way when she impacts the roof from when she first started falling.
