Jessica Chastain admits her sister's suicide completely changed her.
The 'Zero Dark Thirty' actress was devastated when her younger sibling, Juliet, took her own life in 2003 after a long battle with depression, but believes the experience has helped her to stay grounded despite her Hollywood success.
The 37-year-old star said: "It completely changed the person I am. A movie, Oscars, a dress, if someone thinks I'm stupid...I realised nothing is that important."
Jessica attended the prestigious Juilliard School in New York City after winning an acting scholarship provided by the late Robin Williams, who committed suicide last August, and hopes to carry on his "legacy."
She told the January issue of InStyle magazine: "I always thought in some way I would have a chance to pay him back. It was a very strange thing to have never met him. I didn't want to be stalkerish, but then you always question yourself: Did I do enough? I'm hoping there's a way to continue his legacy and keep the scholarship going."
The 'Interstellar' star has no interest in carving out a career in other areas.
She said: "My favourite thing is the world is acting, and I want to be seen as a professional. I don't have a lifestyle website. I'm not interested in the fame of being a personality. Some people are, and they love it, and that's great for them."
