As a psychiatrist treating scores of women (and men) who have worked in just about every position in the entertainment industry, I have heard frustrated confessions from the couch that collectively seem to ask this question: Why am I not further ahead in Hollywood?If we were to look only at statistics, like the ones in a recent study by San Diego State University that examined the top 700 films of 2014, we would come away believing that there is, in fact, an impenetrable celluloid ceiling, with a significant dearth of women in top-billed positions such as director (13 percent), executive producer (21 percent), producer (27 percent) and writer (15 percent). However, there is a large number of women in less visible positions in film and TV — for example, casting directors, whose ranks are approximately 75 percent female, according to the Los Angeles-based Casting Society of America.
