This nature documentary is a 90-minute mini-version of the much longer Planet Earth produced by the BBC. The latter production took five years to make, had a million budget, and employed the latest in photographic technology. The super slow motion and time lapse techniques are especially impressive. Watching the twelve-month transformation of a forest in 30 seconds is spectacular. Earth focuses on three animal "families" — a polar bear and two cubs, a herd of elephants, and then a mother and baby humpback whale that make a 4,000 mile migration. In between these three stories the film intersperses takes from the longer documentary. My only complaint is that this production oversells the product with music that at times is both melodramatic and cutesy, and a corny narration that is clearly intended for young children ("Time for mom and dad to fix breakfast for junior!"). If there is any nature photography that does not need hype, this big screen version is it. Still, like its longer predecessor, Earth makes for fantastic family viewing.
