It's been years since I have seen this movie, but I remember it fondly. I remember being just whiplashed in the sequence where Alda shows up as a bitter anti-war type. Burstyn presses and presses him about why he has changed into a cynical bitter bastard, and he puts her off and puts her off. Finally, the dam breaks, and he tells her, "Because Michael is dead!" That one line, delivered by an actor I normally don't like, still gives me the shivers as I write it. Alda delivered that simple declarative sentence with all of the agony, anger, hurt, and rage that I can imagine any man who loses his son would feel.
