The Center also found that only 25 percent of producers are women. Women also make up just 15 percent of screenwriters, BBC News reported.
Independent films are better, but not much, according to research published yesterday by the Sundance Institute. The institute studied 11,197 directors, writers, producers, cinematographers and editors in US from 2002-2012, and found that just 29.8 percent of the filmmakers were female, according to a press release.
"There has been no sustained or meaningful change across the last 11 years in the percentage of directors or producers at the Sundance Film Festival," study director Stacy L. Smith told CNBC.
The research comes after the Cannes Film Festival came under fire last May, when not a single female director was in competition to win its main prize, the Palme d'Or.
