Atlantis is filmmaker Luc Besson's celebration of the beauty and wonder of the world beneath the sea, expanding upon themes touched on in his film The Big Blue. Combining stunning underwater cinematography and a hypnotic score by Eric Serra, Besson's singular vision defies dialogue or narrative structure to explore ocean life as you've never seen it before. Following the colossal success of The Big Blue, Luc Besson crisscrossed the world's seas and oceans to film the beauty and diversity of marine life: from the giant octopuses of Vancouver to the manta rays of the Pacific (New Caledonia), and the grey sharks of Tahiti. A film with no actors or sets other than the underwater world. A breathtaking view of marine species: sharks, dolphins, manatees, octopuses. An exploration of the seabed in the Bahamas, the Galapagos, Vancouver, and Tahiti.
