“When you have both genders represented, then you have a healthier point of view.”

Oscar-nominated actress Jessica Chastain has long been outspoken about her thoughts on diversity in Hollywood.

"Today is Martin Luther King Jr.'s birthday, so it got me thinking about our need to build the strength of diversity in our industry," Chastain said when she accepted a Critic's Choice MVP Award last January, "and to stand together against homophobic, sexist, misogynist, anti-Semitic, and racist agendas."

Now she's once again speaking out about the importance of gender equality in Hollywood — as well as the revelatory experience of working with women on the film The Zookeeper's Wife. "I can't tell you — it's amazing."

"I've never been on a set with so many women," she wrote.

"We're not even 50 percent of the crew — we're probably something like 20 percent women and 80 percent men — but it's way more than I've ever worked with on a film before."

"I just know that when you have a set with predominantly one gender, whether it be all men or all women, it's not going to be a healthy place."

"I imagine it's the same thing in the workforce or other environments: When you have both genders represented, then you have a healthier point of view."
