Disney bosses will plant 500,000 trees on Earth Day after film fans flocked to buy tickets for the company's new documentary Earth. The executives agreed to plant a tree for every ticket bought during the film's first week. The movie opens on Wednesday and is Disneynature's first film.

Disney boss Mark Zoradi says, "With half a million new trees committed so far, Disneynature's first film is already making an impact on the world - and Earth hasn't even opened yet. We're so pleased that moviegoers have embraced this film and our tree-planting initiative to this degree and we expect the numbers to keep climbing."

The film is narrated by actor James Earl Jones and follows the stories of three animal families as they travel the world.
