Largely created by immigrants, the film industry evolved over its first few decades thanks to the work of people outside the traditional ruling class— immigrants, people of color, women—partly as a result of elites denigrating the fledgling field. As the moving picture industry transitioned from neophyte to powerhouse, young and ambitious rebels energized its output. Mostly written out of history, women provided an important component for popularizing silent film and making it a financial success. Women were integral in producing entertaining films to keep up with exploding demand. Men often resented their power and success, and as the studio system took hold, women found themselves out of favor and replaced. First Women of Hollywood explores the invaluable contributions of these mostly forgotten and unacknowledged pioneers.
