Jessica Chastain thinks Hollywood needs to impose ''quotas'' to address the gender imbalance.

The 'Woman Walks Ahead' actress has vowed to work with at least one female director a year and thinks more people in the movie industry need to follow her lead in order to make things more equal for women.

She said: ''There are self-imposed quotas we should be employing in the industry.

''Justin Trudeau, the Canadian prime minister, has 50% women in his cabinet. When they asked why,he said it was because it was 2015. Or the screenwriter and producer Ryan Murphy; half of his directors are women.

''I've given myself one too, to work with a female filmmaker every year. And I'm going to continue doing that until I see real change. We have to make quotas for ourselves.''

And Jessica, whose new movie 'Woman Walks Ahead' details the real life encounter between a white artist and a Native Mexican, thinks other minority groups need to be pushed into the spotlight.

She told Grazia magazine: ''I want movies about Asian-American actors, I want to see a film directed by an indigenous woman. What can I do for indigenous women? Because they really are the most ignored.

The 40-year-old actress was reluctant to speak out about sexism when she was younger, but has no such concerns now.

She said: '' At the start of your career as an actress, you're too afraid to say anything because you're afraid to rock the boat.

''But once I started working I could see the same behaviour happening to other people. I found I was quicker to say, 'that is not good, don't do that.' ''
