My apologies for the bump, although this is a very good unit by Wyrmshadow.
I have always wondered where The League of Extraordinary Gentlemen came up with the design of the Nautilus that they used, as it is much different from that of Verne in 20,000 Leagues Under the Seas. The movie Nautilus is optimized for surface travel, while Verne's Nautilus was optimized for submerged operation.
I was going through Norm Friedman's US Submarines Through 1945-A Design History, when I got to page 105. There was the movie Nautilus, based on a sketch design for a World War 1 fleet submarine, optimized for surface performance. The book was published in 1993, so it would have been available to the movie special effects people.
Side Note: I was working with Norm on something else at the time, when we met at the National Archives in D.C. while he was also researching the book. I mentioned to him some work that I had been doing on Japanese WW2 ASW, and as a result, I am mentioned in one of Norm's foot notes. Nice to have that.
