Jessica Chastain went to El Camino High School, as well as Sacramento City College before she attended the Julliard School in New York to study drama. She was offered a place, but her family was concerned about the cost. It was a scholarship funded by Robin Williams that helped immensely.
While at Julliard, producer John Wells saw her in a showcase and signed her to a 12-month holding contract. Jessica said, "When I first moved to Los Angeles, I don't think anyone knew what to do with me. I'm not incredibly tall with blond hair. There's something about me that's.different, not modern. Which is maybe why I've ended up doing all of these period movies" (telegraph.co.uk).

For her role in "The Debt," Jessica took classes in krav maga to prepare for the fight scenes. "It was a really good part for a woman, and those are hard to come by in Hollywood.I took German classes, and I read all those books about Mengele and about the history of the Mossad. I totally immersed myself in this character" (telegraph.co.uk).
Jessica Chastain said of making films, "When I first started, I'd think, 'Oh, we're all best friends now, and we love each other.' And I'd be heartbroken a month later when no one had called me back!'"
Jessica Chastain told askmen.com, "I was the girl who never thought I'd be anything but an actor, so what I've really had to struggle with is having patience."
