Una meravigliosa realtà

I saw this on TV many years ago when I was a kid and the ideas have stayed with me like no other story. I think the basic story has the core of a fable for the ages like "Groundhogs Day" or "It's A Wonderful Life". In particular I remember the Idea that some people didn't need the infection. They were capable of happiness all the time ; and some were not. Now thirty years later the research of psychiatry and psychology finds that the basic ability or disposition to be happy underlies much of what happens in our lives. If they had seen this movie. We see constant advertisements for medications to make us happy. The characters in the movie are dated but the basic question of happiness haunts each of us and all of us together. I only wish I could see it again.
