The night before, Jessica was all dolled up for a screening of her highly anticipated film Zero Dark Thirty in the Big Apple.

Jessica recently chatted about the emotions she felt while filming the movie.

“There was a 10 minute break while I cried. I had to go hide behind a building. I just lost it and started crying,” Jessica said. “I know I’m playing this woman who’s supposed to be – it’s her job – to be unemotional, but I still feel things. And I wasn’t going to be able to do the scene again without letting out, without having a good cry.”
