I haven't had the opportunity to follow Sam Shepard's dramaturgical work, but I have been able to follow much of his performance in films based on his plays or scripts. You mean *Fool for love*, which I remember quite well and I was interested not only in the subject, but the performance of Shepard and another actor that I appreciate very much: Harry Deam Stanton, also knowing that it was a film directed by the genius of American cinema that was Robert Altman. The desolate perspective with which love is treated in this work, as well as the theme of affective memory, are also in a film from a previous year (one of my favourites): *Paris, Texas*.  Based on a screenplay by Shepard, starring Harry Deam Stanton and Nastassja Kinski. We are confronted with a vision very similar to that of *Fool for love*.
Thank you for your illustrative post, @honeydue. Greetings.
