Gorilla & Grizzly (DVD)

A masterpiece of expertise and innovation: award-winning cameramen using revolutionary filming techniques, backed by the latest scientific research to reveal two of nature's superstars, revealing aspects of their lives and habitats that have never been seen before.

• Gorilla: Follows three newly discovered gorilla sanctuaries in northern Congo: Ndoki, Odzala and Lossi, in search of the true nature of the lowland gorilla - uncovering as tangled a web of romance and friendship, jealousy and innocence as any human soap opera might contrive.

• Grizzly: Few animals can match the intelligence, power or resourcefulness of the North American bear, or 'grizzly'. This film reveals the more intimate side to the grizzly - how mothers raise and teach their cubs, the playfulness and hardships of adolescence and the "rituals of courtship". Most surprising of all is that every grizzly is its own character in looks, temperament and skills.
