Hollywood's man problem may be a matter of simple math

For all of the hand-wringing over what enabled movie producer Harvey Weinstein's bad behavior for decades, the answer likely lies in the numbers.

Mathematically, Hollywood has a man problem.

Men overwhelmingly dominate nearly every portion of Hollywood, from movie sets to the corporate suites. Of the 100 top-grossing movies released last year, only five were directed by women, according to a USC Annenberg School for Communication and Journalism study. Men received nearly 87 percent of the screenwriting credits, the study found, and 79 percent of the producers were men.

And it's not just movies. Men created three-quarters of the television shows that ran during the 2014-2015 TV season, USC found. And of the 1,550 executive positions in major entertainment companies, men filled more than 60 percent of them, and 80 percent of the highest-powered jobs.
