Even the most scrupulous and exact person may fall victim to mistakes and errors. An allusion to the Greek poet Homer, whose epic poems contain several apparent errors in continuity. The film is without a doubt the filmmaker's masterpiece, despite a minor plot hole in the third act—even Homer nods, after all. Now, even Homer sometimes nods, to be sure, but any errors in this matter, no matter how small, could cost the company millions.
