This is one of my favorite scenes in all of cinema. Pay attention at the 1:40 mark onward, and you'll hear Catherine Deneuve say "Un ange passe," when she senses an awkward pause in the conversation. Hubert, the French Planter, then answers her in French and explains to Willard(Martin Sheen) that he had said, "Let's eat it." "Qu'on de couper." literally means "Let's CUT it."
