Interesting observation. I would assume off the top of my head that the demands of fame would compromise an artist's ability to be meaningfull. Let me ask you what you think about this phenomena of quality actors and directors reaching a certain noteriety and becoming caricatures of themselves. Is that axiomatic within that proffesion? I don't remmember someone like Gregory Peck becoming a shell of himself and his talent; whats going on with these guys. You see a picture with a name star and expect it will be watchable and you are disappointed. Bobby D; Jack; lots more to name. Where are the true practitioners of the craft? Can you picture Spencer Tracy acting the fool in a movie? Ever see the movie, The Cup? Made in Tibet real nice flick.
