Stars are celebrating International Women’s Day on Wednesday in all sorts of ways and in all corners of the world. While some have taken to social media to voice their support for women’s rights, others have taken to the streets to participate in rallies and protests. Jessica Chastain did just that when she stepped out in Warsaw, Poland, to march with the local people. The actress, who is in the country to promote her film The Zookeeper’s Wife, dressed in an all-black outfit to honor the color Poland chose to wear to focus on issues including femicide and abortion. In addition to walking with the crowd, Jessica also chatted to individuals and posed for photos. Who run the world? Well, you know the rest . . .
