In the wild, the killer whale is dangerous to all prey. In captivity, however, it is a source of great wonder and joy to man. An Orca is often essential to the success of a marine park. Veteran filmmaker Nicolas Noxon (Secrets of the Titanic) takes a fascinating underwater look at this beautiful creature in both its native habitat off the coast of British Columbia and in the captive environment of theme parks and aquariums. Witness the killer whales’ beauty, grace and intelligence, and explore the ongoing controversy involved in keeping them captive. As seen on ABC. Narrated by Richard Crenna.
