Audio problem: Just before midnight when the band is playing "Morning After" the camera pans out for a wide shot of the dance floor - the dancers are dancing MUCH too fast for such a slow song - and you do still hear the song.

Factual error: Throughout the end there is fire everywhere. All of that fire would consume any oxygen that was in the rooms and fill the rooms with heavy black smoke. They are walking and climbing everywhere without the effects that the smoke and lack of oxygen would have caused.

Continuity: Just as Susan jumps down from the overturned table, you see a shot of her feet, and she is not wearing shoes. Then when she lands in the curtain, she has her shoes on.

Visible crew/equipment: When Rev. Scott swims up the first stairwell, after pushing aside the dead crew member, as his head comes up the shaft, you can see, very quickly, the flippers of a crewmember swimming out of the shot behind him.
