Few who witnessed the awesome spectacle of the Titanic emerging from the darkness of the ocean depths in James Cameron's Ghosts of the Abyss are likely to forget that spectacular sight, and now the groundbreaking filmmaker journeys even deeper into unexplored territory with this look at some of nature's most elusive creations in Aliens of the Deep. Using the basic concepts of astrobiology as his foundation, Cameron enlists the aid of talented marine biologists and NASA researchers to reveal the fascinating and seldom-seen life forms of the sea and use their biological makeup to create a speculative blueprint for what life on other planets might look like. In the super-heated, mineral-charged water of hydrothermal vents, creatures such as a six-foot-tall worm with crimson plumes dance alongside blind white crabs and some of the strangest creatures you're ever likely to see. If Ghosts of the Abyss brought viewers as close as they're ever likely to get to standing on the ocean floor and beholding the majesty of one of history's most notorious tragedies, Aliens of the Deep brings them as close as they may ever come to standing face-to-face with an alien life form.
