Apparently totes jealous of the Discovery Channel, Disney has launched a new production banner called “Disneynature.” The slate of films will basically be like Discovery Channel stuff we see all the time, but for cinemas instead of televisions…and narrated by Patrick Stewart instead of Sigourney Weaver. For Earth Day 2009, the film, “Earth” will hit cinemas. Co-produced with the BBC, it follows three animals families over the course of a year. Oh, and somehow manages to weave in footage from “Planet Earth” which I’ve had on DVD for ages. Disney’s not trying to reinvent the wheel here, just put a different wrapper on it and see if we’ll bite.
