The Mystery of the Med Rings

A short distance from Marseille, at Cape Morgiou, in the depths of the Calanques massif, lies the Cosquer cave, discovered only about thirty years ago by a diver, Henri Cosquer. With its bestiary of hundreds of paintings and engravings - horses, bison, jellyfish, penguins - the only underwater decorated cave in the world allows us to learn a little more about Mediterranean societies 30,000 years ago. Today, threatened by rising water levels accelerated by global warming, this jewel of the Upper Paleolithic is in danger of being swallowed up. To save the cave from disappearing, the Ministry of Culture has chosen to digitize it. From this virtual duplicate, a replica has been made on the surface to offer the public a reconstruction that allows them to admire these masterpieces.

Created in the Victorian era to widen the mouth of the River Tees for shipping, South Gare is a man-made peninsula extending four kilometres into the cold North Sea. Today, the industry it was built for has gone, but the Gare remains as a haven for all sorts of unexpected communities - kite-surfers, photographers, bird-watchers, scuba-divers and the people who simply appreciate its strange, lonely beauty.

Coral reefs are the nursery for all life in the oceans, a remarkable ecosystem that sustains us. Yet with carbon emissions warming the seas, a phenomenon called “coral bleaching”—a sign of mass coral death—has been accelerating around the world, and the public has no idea of the scale or implication of the catastrophe silently raging underwater.

This film brings to life, thanks to unknown footage from the great American director William Wyler, an important period in the history of Corsica during World War II. In 1944, the Alto base near Folelli was home to both a group of fighter-bombers from the U.S. Army Air Force (the 57th Fighter Group) and the famous French Lafayette fighter group. Day after day, the young pilots of these two units took off from the Alto runway in their P-47 Thunderbolts to attack, strafe, and bomb the German troops who, in Italy, had halted the Allied advance at Monte Cassino and participated in the Provence landings in August 1944. Isabelle Clarke and Daniel Costelle tracked down the pilots, and sixty years later, these pilots are reunited...

As well as providing the subject for Luc Besson’s The Big Blue, Jacques Mayol did more than anyone to establish the sport of free diving to enormous depths without an oxygen supply. Using breathing techniques derived from yoga, he went to 50, 60, and even 100 meters—depths no one had considered to be within the bounds of human possibility. Mayol was a sportsman, a mystic, a vagabond, but above all, a man who believed in testing the limits of experience. This visually stunning tribute shows a man’s quest to be at one with the vastness of the ocean and to have no fear of the abyss within, where lurks serenity, freedom and finally, death.
