Because he is one of Hollywood nice boys....he never did anything naughty when he was "at the top" and he doesn't care to do anything naughty now that he is relatively old and almost gone completely from Hollywood, it seems. Some celebs rather remain in peace and private than to share everything and create "news" about themselves. He is a quiet one. When there's no butter to spread, what is the point of placing a slice of bread on a plate....I guess that is why people don't "talk" about him.
