I found a beautiful short film on The Serengeti National Park. You can watch it for free at: http://www.hulu.com/watch/27957/africa-the-serengeti
Its narrated by none other than James Earl Jones! I thought it was a good film but the quality is, of course, less than DVD quality. This video won't be on hulu forever, so watch it ASAP.
Apparently the soundtrack was done by Hans Zimmer. I dunno if Lebo M helped or not.
Enjoy
