Sunday is Earth Day, and as a result, Hollywood is offering such nature-oriented entertainment choices as the Disney ape documentary Chimpanzee and the IMAX short film To the Arctic 3D
. But a third and decidedly more indie option is One Day on Earth, a grassroots documentary that compiled more than 3,000 hours of footage from every country in the world and whittled it down to a 104-minute movie. The footage was shot by more than 19,000 amateur and professional filmmakers during the course of a single day: October 10, 2010. And now the film will be screening this Sunday at select theaters in more than 160 countries.
