It's possible that Generation Facebook, accustomed as it is to a whole range of experiences that it only imbibes online, doesn't have the same need for physical interaction in order to be creative as previous generations still do. It's possible that Generation Facebook can co-create and collaborate quite happily from afar.
Working with Chaplin was very amusing and strange. His films are so funny, but working with him, I found him to be a very serious man. Whereas the films of Hitchcock are macabre, he could be a very funny man to work with, always telling jokes and holding court. Of course, when I worked with Charlie he was getting older.
