In the scene where the passengers are sliding down the deck (as the ship becomes vertical)one of the passengers hits the large 'steel' post thing (I don't know the proper term for it, but it may be used to tie the ship when docking.) and it bends. The passenger bounces off and continues down the deck.
I think in one of the other listed slip-ups somebody said something about it being rubber and that James Cameron replaced everything that was actually, in real life, steel or iron with rubber so that the actors/actresses wouldn't get hurt.
The people falling into the stuff on the ship weren't even real people-they were dummies made for the sequence when people were falling down the ship and hitting things..
This is confusing me. IF they were dummies, then why would they bother making the whatever-you-called-that-thing out of rubber? Also, in a different Slip-up, someone mentioned that actors were on skateboards. Why would they put dummies on skateboards? Please don't say, "To make them go faster," because, if they were dummies, they wouldn't shoot the scene horizontal and show it vertical.. as they do in scenes like this when they use actual people.
