Earth (G) **½

Roger Moore, The Orlando Sentinel

Earth, the first film from Disney's new documentary unit, Disneynature, covers every corner of the natural world. It's a grab bag of beautiful nature footage, narrated by James Earl Jones and compiled from the BBC's Planet Earth series. We meet funny birds of paradise and cuddly penguins, but also a doomed polar bear and a shark dining on seals. Wolves chase caribou and a cheetah runs down a gazelle. Nothing too graphic, but it creates drama.

The footage is striking -- stunning Alpine vistas, sweeping desert landscapes, flocks in mass migration and vast herds of critters avoiding predators.

There is a message to this film about a fragile ''changing planet'' -- the planet is getting warmer. That's why polar bears are drowning or starving, why deserts are expanding and elephants are dying of thirst.

The film is rated G and runs 90 minutes.
