What's the Story?
ALIENS OF THE DEEP documents efforts by scientists to explore parts of earth where the sun never shines. The goal is to find life forms that exist without photosynthesis, the light-based process that results in food for animals on earth. Collaborative marine biologists, space science experts, and other researchers discover lots of life 3,100 meters below the surface of the ocean, sustained by chemosynthesis. In a symbiotic relationship, it turns out, sea life feed off bacteria that feed off the sea life. When animals grabbed by an ingenious robot in the deep sea are brought back to the lab, they are subjected to the simulated environment of Jupiter's moon Europa to see if life could also survive there. The submersibles and gadgetry are impressive. The subs that carry Cameron and NASA and other scientists to the ocean's depths roam the waters like space ships. One of Cameron's brothers created a box-like bot that scientists can launch undersea to get into hard-to-reach places for a look through the bot's camera at submerged volcanoes and the bizarre creatures living in the surrounding hot waters.
Is It Any Good?
This is an achievement as a film but more impressive is the deep-water exploration itself that the film focuses on. Director James Cameron (Titanic) is an avid explorer, having designed a submersible himself, and in conjunction with National Geographic, he's traveled with the sub 35,000 feet down, deeper than any other human. He has put his energy and funds into helping established scientists at NASA, the Jet Propulsion Laboratory, and others use information he's gathered to propel our knowledge forward. The story jumps around quite a bit, as it ties in different areas of research and that may present a challenge to younger views trying to follow along, but stunning visuals go a long way toward keeping Aliens of the Deep interesting.
