Born in 1930, Clint Eastwood did his most critically acclaimed work after he was 60. That included "Unforgiven" [1992], "The Bridges of Madison County" [1995], "Mystic River" [2003], and "Million Dollar Baby" [2004]. Not that his acting and directing were mediocre before then. It's just that they never reached the greatness of the later performances and vision.
This question of late blooming is coming up a lot. University of Chicago economics professor David W. Galenson researched and wrote about it in "Old Masters and Young Geniuses." Galenson's theory is that some with talent get their direction on how to apply it young, as with Mozart, and some struggle with that direction until they are older, like Hitchcock. Then the genius bursts forth.
For Eastwood that doesn't seem to be the explanation. His blossoming seems more built on his ability to simply keep growing. Remember he was a big name even before "Unforgiven." The issue seems to be why does a man like Eastwood keep growing when many others stop or never start?
In his new biography "American Rebel: The Life of Clint Eastwood," Marc Eliot depicts this actor and director as someone who wasn't constrained by public opinion, convention, or the assumption that someone or something was going to help him get what he wanted. Reared during the Great Depression, Eastwood seemed to conclude that he had to look out for himself and he would do that in his own way. And he never wasted energy defending anything. To call his marriage "open" would be an understatement. He never concealed his affairs. He just didn't care what others thought.
Perhaps that's the "secret" for us geezers to remain creative and, more to the point right now, employable: Be determined to take care of ourselves, do it our way, and don't be the least bit self-conscious about what the world is clucking about. Those of us who have stayed in the game or had amazing comebacks - Steve Jobs, T. Boone Pickens, Lou Dobbs, Bill Clinton - seem to live that.
Had they paid attention to anyone or anything but themselves they might have surrendered to society's expectation that they are finished.
