I know that the grand staircase in the movie was a copy, but bigger than the original, but I only remember seeing the grand staircase down to D Deck and the elevators to E Deck. I do remember a little of the grand staircase double trace, but I was not sure why they didn't film that section of the E Deck set. Was that part not the squared like the original and curved like the other levels for the movie, or what?
