Curt, sorry that I did not post a link to the Eloquent Nude DVD. I posted it on the LF forum last week; it was available at the screening in the SFMOMA bookshop.
To your question of the actors and the portayal of Edward and Charis, I can say that the film is an honest representation of events. It is primarily a blend of stills, narration, and and a bit of acting to give it life. The actors are not professionals, the chap who plays Edward is a photographer who bears a strong resemblance to him, and the young woman likewise to Charis.
Charis was present at the screening and gave the film high marks; she should be the best judge of its worth.
