After producing MICROCOSMOS, THE MONKEY FOLK and WINGED MIGRATION, French filmmaker Jacques Perrin trains his camera on the world’s oceans and the creatures that inhabit them, evoking their splendor, suppleness and speed, but also their vulnerability to environmental threats.

Over four years Perrin’s production company Galatée travelled the globe with a team of divers, technicians and scientists, using 21st century technology to bring us a documentary that penetrates the mysterious and fascinating marine world like never before.
