If I raise this matter of images it is rather to give you some idea of how the movie mind works. It has to feel its way through the appearances of things, choosing, discarding and choosing again, seeking always those more significant appearances, which are like yeast to the plain dough of the context. Sometimes they are there for the taking; as often as not you have to make a journey into a far country to find them. That, however, is no more difficult for cinema than for poetry. The camera is by instinct, if not by training, a wanderer.
