" Women were never absent from film history; they often simply weren’t documented as part of it because they did “women's work”, which was—by definition— insignificant, tedious, low status, and noncreative. In the golden age of Hollywood, women could be found in nearly every department of every studio, minding the details that might otherwise get in the way of more important, prestigious, or creative work (a.k.a. men's work).
If film historians consider the classical Hollywood era’s mode of production a system, we ought to consider women this system’s main-stay, because studios were built on their low-cost backs and scaled through their brush and keystrokes. "
