The waters surrounding the Azores region of the Atlantic Ocean are the habitat of a legendary creature: the sperm whale, the subject of Melville's classic novel Moby Dick. For decades, whale hunters harpooned herds of these magnificent creatures, pursuing them from the United States to the remote waters of the mammal's favorite sanctuary — the Azores. The species, though elusive, has been making a comeback, and the area is now a wonderful place to observe and photograph these legendary animals. Whales of Atlantis documents a five-month voyage aboard the French ship Belem. Explorer-filmmaker Jean-Christophe Jeauffre and his crew retrace previous expeditions in search of the sperm whale, ultimately photographing some in a remarkable undersea encounter. The documentary includes extensive history about whaling in the area and looks at the remnants of a once mighty industry that came to a halt when the international community moved to protect the sperm whale and other species.
