This beautifully shot documentary gives Imax viewers an idea of the how big these giants of the deep really are. There is rare footage of blue whales, along with few shots of killer whales and the smallest "toothed whales," aka dolphins and porpoises. The main part of the documentary follows the science ship Odyssey as she tracks two right whales, mother Misty and calf Echo, as they take the dangerous annual trek from Hawaii to their feeding grounds in Alaskan waters. The photography is breathtaking, with fascinating underwater shots and fantastic aerial footage. The scenes of whales feeding was really neat, and has to be seen to be appreciated. I went to see this film with about 300 elementary children, kindergarten through sixth grade. At times, you could hear a pin drop in the theater as all of the kids sat in rapt attention. "Whales" is a must see for anyone who loves whales, water or oceanography. Take the kids. Any movie that can keep that many school children quiet and well-behaved (without any threats or bribes) is well worth the price of admission!
