When nature removes a great man, people explore the horizon for a successor; but none comes, and none will. His class is extinguished with him. In some other and quite different field, the next man will appear.
A lot of the times the first take was the best, because the actors are not analyzing themselves as much; they just do it. I believe in happy accidents and I'm not necessarily into actors getting the dialogue exactly as I wrote it; I'm much more into them understanding the motivations and have it come out in a natural way, and maybe catch something that I didn't expect.
