At a TIFF press conference for the psychological horror film — which also included director Darren Aronofsky (Black Swan, Noah) — Lawrence was asked what advice she would give her younger self.

Lawrence has been an advocate for female actors receiving equal pay since emails from the Sony Pictures hack revealed that she was paid substantially less for 2013's American Hustle than her male costars, despite arguably being the movie's biggest star.
She wrote about the incident in 2015, saying "I failed as a negotiator because I gave up early."
