MH, the Polio movie that airs on Sundance every now & again is called 'The Origin of Aids' and it's a fantastic documentary about scientists involvement in formulating the aids virus. It's based on Edward Hooper's book 'The River: A journey back to the source of HIV and AIDS'. The book is long out-of-print and fetches a good amount of money when available. The movie was never commercially released due to science and pharma influence. I can get you a copy of the dvd if you're interested.
