When Donated to Science was shown on Television here in New Zealand it was the highest rating documentary of the year – a third of the adult population watched it and talk radio, went mad within a few minutes of broadcast. It garnered stunning reviews and was a RealScreen ‘Pick of MIP’ there’s a clip here http://www.realscreen.com/screeningroom/20090930/donated2science.html
