I only saw that movie once, decades ago, but it left a lasting impression. I'm a sucker for Robert Redford/Sydney Pollack stuff.
I even like this here! It gave me goose bumps just watching it again now (actually I have rewatched it twice more today and the goose bumps returned everytime!):
That could have been (probably is) our own Herr Westheimer, you know, who gave up one of his great loves for political convictions (or lack thereof!) too ... How a Che Guevara poster on a refrigerator came to stand between two hearts meant for each other ... sigh! Dave, will you retell the story please for the benefit of the true romantics among us?
