One can't be sad. He lived an extraordinary life and had rounded off his life's work. In an interview he gave a year or two back he was saying how he looked forward to seeing his wife again.
He directed his first great movie (we might argue which of several contenders deserves the title) over 50 years ago and the last (Saraband) as recently as 2004.
He was one of the greatest artists of our times. I think he stands for our times the way Shakespeare, Goethe, Dickens stand for theirs. He had integrity. He had honesty. He was like no-one else.
