“For 25 years, I've been the only woman on set, so I had no other women to talk to ... They call it 'Smurfette Syndrome.' Because she's got a hundred Smurfs around her and she's the only girl," Reese explained.

For the actress the experience of making ‘Big Little Lies’ was a totally different on set vibe."Honestly, it's so refreshing to get to spend time with women,” she said.

Speaking about the need for women's stories to be told in Hollywood Reese continued: ”We learn from art, and what can you do if you never see it reflected? Things have to change — we have to start seeing women as they really are.

“We have to see real women's experience. Whether it involves domestic violence, whether it involves sexual assault, whether it involves motherhood or romance or infidelity or divorce. We need to see these things.”
