The Silent World will expose discoveries that are as vibrant and beautiful today as they were when first exposed 50 years ago. At the film’s beginning, viewers follow a group of scuba divers wearing a new Aqualung technology to their destination, a motion-picture studio 65 feet under the sea. However, this studio has no actors, backdrops, or special effects. Instead, there are the divers themselves and the diverse variety of sea creatures that surround them. Their continually changing backdrop also includes the endless depths of the Mediterranean Sea. Later, the diving crew resurfaces and takes the film aboard Cousteau’s research ship, the Calypso.
