there was a documentary last night on BBC 1 called "Imagine: Annie Leibovitz - Life Through a Lens"
it's available on bbc.co.uk/iPlayer for the next 6 days .... but I think you need a uk IP address to view it, although I understand there is something clever people can do with a "proxy" server? out of my league, but if someone here knows what a poxy server is then fire away. I dont know what the doc is like yet, but I'm watching it now. Might be of some interest.
