Jessica Chastain Opens Up About Her Younger Sister's Tragic Suicide

Jessica Chastain is ravishing in a red floor length dress at the A Most Violent Year premiere held at Florence Gould Hall Theater on Sunday evening (December 7) in New York City.

The Oscar nominated actress was joined on the red carpet by her co-star Oscar Isaac, writer/director JC Chandor, Girls stars Christopher Abbott and Zosia Mamet, model Lindsay Ellingson, actor Zachary Quinto and actress Megan Boone.

Jessica recently opened up about her younger sister’s suicide. She tragically suffered from depression. “It completely changed the person I am,” Jes told InStyle. “A movie, Oscars, a dress, if someone thinks I’m stupid…I realized nothing is that important.”

FYI: Jessica is wearing an Armani Prive dress, Giuseppe Zanotti shoes, and a Piaget necklace.
