The on-screen chemistry between Glenda Jackson and George Segal is magical. This is the kind of affair everyone fantasizes about. The way the story unfolds and flows is quick and reveals all the interesting aspects of these two people who are accidentally thrown together. There is a very physical lovers' quarrel that will have the viewer laughing convulsively. There are also tears. The "Voice of Reason" in the movie is the character we both love and hate. I lost count at 31,the number of times I have watched this movie. After all these years, it is still one of the great love stories.
