Disney's newish nature arm---oh African Cats, we can't wait to roar for you---re-releases this multi-country co-pro in honour of Earth Day. Narrated by Pierce Brosnan, Jacques Perrin and Jacques Cluzaud's Oceans traverses the normal Lorne Greene territory of baby turtles crawling out of the sand, cavorting dolphins, lounging (and hilarious) sea lions. And then the killing starts. Orcas eat seals, crabs eat each other, sharks eat everything. There's surprisingly small amount of eco finger-wagging and a touch too many suspicious reaction shots---a rocket's red glare reflected in the eye of an iguana, seriously?---but Oceans is marvellously, fantastically shot (very little blood, parents) and foleyed, heavy-handed soundtrack aside.
