The beauty and mystery of life beneath the surface of the ocean is brought to the screen in this documentary, shot in 3-D and exhibited in the form of high-definition IMAX film. Shot in the deep ocean off the coast of Baja California, the Caribbean, and North Carolina, deep sea represents the complexity of underwater ecosystems, as some sea creatures live in cooperation while others feed weaker species to survive.
Filmmaker Howard Hall also focuses on the splendor of this world rarely seen by human eyes, photographing a number of rare species of fish, squid, rays, jellyfish and other aquatic creatures as well as offering a perspective on environmental hazards that threaten the underwater community. Johnny Depp and Kate Winslet provide the narration of the film.
