Luis Buñuel said this quote
“ As inexplicable as the accidents that set it off, our imagination is a crucial privilege. I've tried my whole life simply to accept the images that present themselves to me without trying to analyze them. I remember when we were shooting That Obscure Object of Desire in Seville and I suddenly found myself telling Fernando Rey, at the end of a scene, to pick up a big sack filled with tools lying on a bench, sling it over his shoulder, and walk away. The action was completely irrational, yet it seemed absolutely right to me. Still, I was worried about it, so I shot two versions of the scene: one with the sack, one without. But during the rushes the following day, the whole crew agreed that the scene was much better with the sack. Why? I can't explain it, and I don't enjoy rummaging around in the cliches of psychoanalysis. ”
