Mistake in "The Cooper-Nowitzki Theorem" (02/06) in The Show Posted July 23, 2009 Could be! I know for the movies there's someone in charge of making sure that anything that happens to clothes and props (dirt, rips, wetness, food spills, etc.) looks the same from take to take or scene to scene. Maybe in this case it would be the director or his assistant since this example depended on Ramona taking the food boxes out of the bag in the same order. On second thought, since the order the boxes were taken out depended on how the boxes were packed in the bag, it was probably the person who prepares the props and who would have re-packed the bag between takes. Does the Grip do this too? It would be interesting to find out. By the way do you know what a "Best Boy" actually does?
