Outdated assumptions--that films are mass entertainment, that large corporations make them--and a context limited to studios and stars makes this a product of the Thirties and Forties, but past the ""plush comfort"" of the front office there's a practical look at scheduling, shooting, recording and editing. The day on a set and on location is briefly indicative, the interpretation of a shooting script more informative. Technical explanation is cursory; altogether (and it isn't much) the focus is on personnel, procedures, problems. For nine- and ten-year-olds this seems mostly irrelevant--and how many are attuned to the old-time Hollywood mystique?
