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 high-definition IMAX film format. Shot in the ocean depths off the coasts of Baja, the Caribbean, and North Carolina, Deep Sea depicts the complexity of the underwater ecosystem, as some sea creatures live in cooperation while others feed upon 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, squids, manta rays, jellyfish, and other aquatic creatures, as well as offering a perspective on the environmental dangers that threaten the underwater community. Johnny Depp and Kate Winslet provide narration for the film.
