Hey, just a head's up/warning to anyone who hasn't seen "The Abyss". Make sure you see the extended version (28 extra minutes)/director's cut version. The theatrical release had the explanatory stuff cut out as the studio wanted James Cameron to cut costs. It made NO sense and everyone in the theater went "HUH?" the end. It would likely have been a huge blockbuster had the additional material been included.
I accidentally came across the extended version in the library, watched it a said to self:
"Wow! So THAT'S what it was about and what a cool movie!"
Sure it's a bit dated, but don't cheat yourself out of a more complete version.
In the same vein, "Hitler's Lost Sub" is the Nova PBS re-enactment version of "Shadow Divers". If you haven't read the book read it lst! Incredible book. Impossible for many to put down and the H.L.S. DVD will contain too many spoilers with less than half the drama and excitement!
In fact be sure to read the book before it's released (S.D.s) as a movie.
