Planet Green orders more 'Greensburg'

Leonardo DiCaprio exec produces series

Discovery Communications' Planet Green has ordered six more episodes of "Greensburg," which chronicles the rebuilding of Kansas town that was devastated by a tornado last year, network president/GM Eileen O'Neill said during Thursday during the TCA press tour.

The series, exec produced by Leonardo DiCaprio, is in the middle of its initial 13-episode run, and the six additional episodes will air starting in May, the two-year anniversary of the tornado.

In addition, Jimmy Buffett has partnered with the network to create a video bringing attention to the plight of sharks that will employ his song "Fins."
