QUOTE : That is the thing about films. They don't change. The immutability of the film (or a book or a painting or a piece of music) is something to measure yourself against. That is one of the things a great work of art does. It stays there waiting for you to come back to it, and it shows you who you are now, each time a little different. But when it is your own film, it isn't immutable. It feels part of you, and so seems to change with you. The filming, the editing, the showing: all of it looks different to her.
