When a scene is being shot, it is very difficult to know what one wants it to say, and even if one does know, there is always a difference between what one has in mind and the result on film. I never think ahead of the shot I'm going to make the following day because if I did, I'd only produce a bad imitation of the original image in my mind. So what you see on the screen doesn't represent my exact meaning, but only my possibilities of expression, with all the limitations implied in that phrase. Perhaps the scene reveals my incapacity to do better; perhaps I felt subconsciously ironic toward it. But it is on film; the rest is up to you.
