"Call of the Killer Whale," a two-hour documentary airing on PBS, begins by focusing on the story of the world's most famous killer whale, Keiko, the star of the film "Free Willy," who was famously set free after being rescued from a Mexican circus. Keiko's story is useful to illustrate the challenges of reintroducing an orca into the wild, having to teach it how to feed off live fish (as opposed to dead ones tossed regularly into its mouth) and how to develop other survival skills basic to wild orcas. The message we take away from the first part of the film is that captive whales rarely live very long and have a tough time of it if they're reintroduced into the wild. Keiko made it to 27, before succumbing in a Norwegian fjord. The second and more powerful part of the film looks at the drastically shrinking orca population around the world and attributes the decrease, inevitably, to pollution and human enterprise that upsets nature's delicate balance. Although PCBs were banned in the '70s, the chemicals, as well as other contaminants in the air and water, can remain in an orca's system for decades, which has resulted in calves born with birth defects. The more challenging issue, and the one that even more tellingly shows the fragility of nature's interconnectedness, has to do with the fate of the salmon population. In the Pacific Northwest, for example, salmon have been the orca's main source of food. We all know that the salmon population is decreasing, but as Cousteau and other scientists contend, part of the reason the fish are decreasing is that man has created salmon farms which have actually hurt wild salmon because the cultivated fish hog all the food in shared waters.

A documentary about the Atlantic Ocean, which tells of the coastal inhabitants' struggle with the sea, the secrets of the deep, and the benefits of the ocean.

The undersea world has often been depicted as a dangerous place filled with lethal predators. A world where sharks are mindless eating machines. A world where the only relationship between species is that big fish eat little fish. Of course, stories of sensational danger and violent predation are seductive to wildlife film audiences. But is that what the ocean is really like?

The people of a fishing village is about to witness a miracle thanks to the new mysterious friend of a young, lonely boy.

When a government representative announces that he intends to reunite an orphaned orca with his pod by transporting him hundreds of miles over dry land, the Mowachaht-Muchalaht First Nations Band, which believes that the spirit of their late chief resides in the majestic ocean mammal, does everything within their power to thwart the controversial plan. As the community grows increasingly divided over how to handle the situation, a young aboriginal boy wrestles with his own identity and new Band chief Mike Maquinna prepares for the trial by fire that could shape his entire future.
