The idea that death lurks everywhere, and nowhere, silent but deadly...

When I was a kid, I remember watching the Disney Film, "20,000 Leagues under the sea", by Jules Verne. The idea of hiding under the waves of the ocean to explore was cool to me. Later, I remember watching a t.v. show that had a sub with a huge window in the bow. I've been reading and playing sims about subs ever since.

Voyage To The Bottom Of The Sea. It was originally a movie as well.
