Analysing the top 100 movies of 2016, the report found that only 31.4% of speaking characters were women, while non-white groups accounted for 29.1%.
Only 4.2% of directors in the 2016 films studied were female, and none of the titles were directed by black women.
The report also indicates major problems concerning intersectionality on screen, with nearly half of all the 100 top films of 2016 completely lacking black female speaking characters, while two-thirds or more had no Asian women and Hispanic women.
Hollywood is still underrepresenting women, disabled people, lesbian, gay, bisexual and transgender people and those from ethnic minority backgrounds, both on screen and behind the camera, a major study on diversity has found.
