this is how I got my dvd of the movie
I had been hoping to run into a copy of this movie for more than twenty years since the last time I had seen it on PBS (channel 13 in New York). I found myself in the website of a company called Alibris (www.alibris.com) originally looking for something else and entered the name in the website search on the off chance that it would be available as the company bills itself as a place to find obscure books/videos/dvd's and lo and behold, it came up as available. So, of course, I ordered it on line then and there. The dvd is issued by Kino on Video "The Best in World Cinema" (www.kino.com) as part of it's "The American Film Theatre" series.
I don't know how many copies of it are out there, but if you're looking for it -try those two websites and goodluck to you!
If you are able to get a hold of it, please respond to this post. I would like to know if my post was of any help to you. Thanks.
