Clint Eastwood is aging beautifully. But someone like Burt Reynolds and others are practically destroying their faces in the amount of work they have.
I discovered that in a story I could safely dream any dream, hope any hope, go anywhere I pleased any time I pleased, fight any foe, win or lose, live or die. My stories created a safe experimental learning place.
For me and for I'm sure any actor, each role is a different challenge to prepare for in a different way.
