Staircase in sub???
Look at sub from the bow, then watch any interior bow window scene for room perspective
Just ain't possible is it to have that many steps?
I didn't notice that it looked out of proportion. But they mentioned in the blu-ray commentary that Irwin Allen took a tour of the USS Nautilus and was so impressed by its huge staircase that he insisted the Seaview have one like it. Maybe he said "...and I don't care if it's physically impossible, just do it!"
shareI have been on the nautilus. Don't recall a staircase. But it was a museum when I was on it. I lived on a sub for 4 years. Believe me, the size of the rooms and some other things concerning the sub are quite unrealistic. All I recall was straight up and down ladders or regular staircases. Again, all much much smaller than anything you would see on the seaview. To have rooms the size you see on the seaview that boat would have to be 3 times as big as it is shown.
shareBTW, that spiral staircase had no outside railing. If the sub pitched or rolled (and it certainly did in this film), anyone on the stairs would have been thrown down to the deck and probably would have suffered a skull fracture or broken neck. In comparison, the spiral staircase on a Boeing 747 has an inner and outer railing. Can't have the passengers & crew falling during turbulence.
