Dolphins and Whales 3D: Tribes of the Ocean

At first glance, dolphins and whales seem like an unlikely choice for the 3D treatment, since the ocean doesn’t offer a lot of the necessary depth cues—you’ve got the swimmers against a characterless background of water. But the first time a camera cruises down the side of a whale, that objection falls away. The narration (read by Daryl Hannah, sounding oddly like Laurie Anderson sans irony) falls into a repetitive structure for each species (they’re beautiful, they’re endangered, repeat), but as educational conservation films go, it’s pretty effective.
