Ingo J. Biermann is making a movie called "Voice - A Sound Journey with Maja Ratkje", planned for release in 2011. I just steal this description: "A cinematic feature documentary about Norwegian composer and performer Maja Ratkje. It is not only the portrait of a singular musician and singer, but the film will explore the sound and the nature of the human voice in all its facets".
A tweet on Ratkje´s Twitter seems to indicate that a small (?!) amount of money is needed to finish it, but hopefully that will happen!
