While many people think the world underneath the sea is a quiet and tranquil place, it's actually buzzing with activity, as different species of aquatic animals propagate their kind, battle for survival, and struggle with the many dangers beneath the surface of the ocean. Into the Deep is a documentary -- originally shot and released in the high-definition IMAX film format -- which dives into the waters off the coast of Southern California, and captures on film the adventure and excitement of life in the waters. Kate Nelligan narrates. ~ Mark Deming, Rovi
