However, after watching all the films in competition and casting her vote for some of the festival's most prestigious awards, she had some troubling things to say about the women she saw represented.
The Zero Dark Thirty actress served as a member of the jury at the 70th annual French film festival, and at the closing press conference, Jessica confessed she wasn't impressed with how women had been portrayed in the films she watched.
Chastain clarified that there were some exceptions, but went on to say, "for the most part I was surprised with the representation of female characters on screen in these films".
"This is the first time I've ever watched 20 films in 10 days, and I love movies", she started.
She was responding to a reporter's question about the female filmmakers at this year's festival, and began by saying that if there was more "female storytelling", there would be "more authentic female characters". "They are proactive, have their own point of view and don't just react to men around them", she added, her words quickly going viral on Monday. The film is the first time a major summer superhero movie has a female star (Gal Gadot plays the title role) and is the first of its kind to be directed by a woman (Patty Jenkins). "They have their own point-of-view".More news: Trump expected to pull US from Paris deal

Chastain's remarks were heralded on social media by several notable female storytellers, such as Ava DuVernay and America Ferrara. Coppola is the second female director to accomplish this task in 71 years.
To be fair, Chastain's comments about women brought nods of agreement from several of her fellow eight jurors, including jury president Pedro Almodovar. Late previous year, the actress opened up to ET about her 2016 film, Miss Sloane, explaining that the depth of the role is what most drew her to the character. In fact, it was "disturbing", according to actress Jessica Chastain.
This year's festival included an increase in female-led projects.
Chastain was spot-on when she observed there was a dearth of female storytellers in the Palme competition - just three of the 19 directors were women.
