Jessica Chastain has confirmed that she is not involved with the upcomingThe Seven Husbands of Evelyn Hugo movie. In a video posted to social media, Chastain was asked to sign a copy of the Taylor Jenkins Reid novel while at the stage door for her production of A Doll's House. For years, fans have campaigned for Chastain to play Celia St. James, a fellow actress who plays a key role in Evelyn Hugo's life. Chastain declined the fan's request to sign the book, saying "I can't sign that, just because I'm not doing it," and later took to Twitter to further explain why.
