Need to Know: Jacques Cousteau's World Without Sun

I figure since I posted Cousteau's other Academy Award winning theatrical release I should post it's sequel, World Without Sun from 1964.  This beautifully shot documentary details Cousteau's daring saturation diving experiment entitled ConShelf II or Continental Shelf Two in the Red Sea off of Sudan.  In it, six "oceanauts" spent around a month at 10 meters underwater doing research and of course filming the picture.  It's an absolute diving classic with every Cousteau-ism you could possibly hope for and lots of solid watch shots. Hopefully the YouTube link plays along but first of all, one of the greatest posters in movie poster history.
