The Internet Movie Database (IMDb) has adopted the “F-Rating” system to highlight the role of women in film.

According to The Independent, the system was invented by Bath Film Festival director Holly Tarquini in 2014 and has since been picked up by 40 movie theaters and festivals in the United Kingdom.

21,800 films have been tagged with the F-rating so far on IMDb, a site which sees more than 250 million visitors per month. A film that is either directed by a woman, written by a woman or features “significant women on screen in their own right” will be tagged with the new rating.

Films like “Frozen,” “American Honey” and “Bridget Jones’ Baby” have been triple tagged given that they satisfy all three requirements. Other marked films include “Freaky Friday,” “Kung Fu Panda 2” and “The Girl on the Train.”

“The F-Rating is a great way to highlight women on screen and behind the camera,” IMDb founder and CEO Col Needham said.

“The F-Rating is intended to make people talk about the representation of women on and off screen,” Tarquini said. “It’s exciting when new organizations decide to join us in shining a light both on the brilliant work women are doing in film and on how far the film industry lags behind most other industries, when it comes to providing equal opportunities to women. But our real goal is to reach the stage when the F-Rating is redundant because 50 percent of the stories we see on screen are told by and about film’s unfairly under-represented half of the population – women.”

IMDb has not yet responded to TheWrap’s request for comment.
