Not only do I not remember anything about this movie, I saw it on Christmas Day, so one would think that I might perhaps remember that.
Add to the fact that the United Artists Riverview was not anywhere near where I lived and/or where I would usually go to the movies, and you have a double - or perhaps triple - mystery. I did, however, go there a few times, but not more than three.
I just looked it up on IMDB, and that jogged my memory somewhat, but considering that Marcello Mastroianni was in it -- and who doesn't love love love him? (answer: nobody) -- I REALLY should have remembered it.
What I also do not remember is who I saw the movie with, which is a shame.
