Although the Earth DVD does indeed contain breathtaking natural history footage, it is merely a selection of scenes and outtakes from the recent Planet Earth series with a different narrator (Patrick Stewart). And yet the sleeve notes seem to imply that it's a completely new package: "Five years in the making, filmed in 200 locations in 21 different countries, the production of Earth took 40 specialist crews, involved thousands of hours of footage and 250 days of aerial photography".
Five years in the making? 40 specialist crews? Hmmm... Earth was clearly put together quickly and cheaply in an editing room - it is no more than a shortened, watered down, inferior version of Planet Earth.
I'm afraid I'm giving this only one star because of the dishonest, misleading packaging! Sales and marketing guys - dontcha just love 'em... :-(
