"World Without Sun" is the second feature-length documentary by legendary diver, ecologist and champion of marine conservation Jacques Cousteau. Filmed entirely beneath the waves, using groundbreaking techniques and technology, the film was the winner of an Academy Award in 1964 for Best Documentary Feature. The film follows Captain Cousteau and his team of divers, scientists and submariners as they spend a month living and working within and around Conshelf Two, a man-made structure rooted to the bed of the Red Sea. In an amazing experiment to determine the effects of living underwater, Cousteau and his crew of 'Oceanauts' must deal with the pressures - both atmospheric and psychological - that come with a job like no other. Cousteau was a pioneer in every sense, developing new technologies in order to push the boundaries of human experience. World Without Sun shows him at his most adventurous, diving deeper than anyone had ever been to explore new worlds, find new creatures, and document this brave new world where the sun never shines. The result is a fascinating, moving and awe-inspiring perspective on the world beneath the sea.
