My father's battle with Alzheimer's. You start with a 600-acre ranch and wind up in the den. What I've learned from his struggle

NO ACTOR EVER FORGETS A ROLE, SO I SHOULD HAVE realized something was wrong. It was late in 1993 and we were having dinner with my father. We were discussing a 1950s film he made, "Prisoner of War." For years he had told me about the gruesome tortures inflicted on American prisoners by the North Koreans. But now he seemed to be hearing me tell the stories for the first time. Finally he looked at me and said, "Mermie, I have no recollection of making that movie."
