I too once saw this movie and can not really understand why it is unavailable for purchase. Don't want to write a spoiler but it is one of the best movies I can remember with Beau Bridges and John Mills. The story is one of the most unique I have ever seen portrayed. Probably Jane Merrow's performance explains this uniqueness and it is her performance that I would most like to experience again to understand her character's purpose and my personal intrigue in examining it again against the recollection of the period and its historical conveyance. Periodically I return to IMDb hoping for the announcement of its availability and where I can purchase it.
