Talented, smart and Oscar nominated, Jessica Chastain is definitely having a moment. The Help, Lawless, The Debt, The Tree Of Life, Take Shelter... she's been a stand-out in every film she's appeared in. It's a McTiernan Run that, with Zero Dark Thirty, has brought her to the attention of the world. But as she explains to Empire, it hasn't been an easy ride. The demands of its subject matter, including scenes of torture and the controversy that has enveloped the movie like an acrid fog, have made this the toughest project to date for the Californian actress. Luckily, she and her director had a cunning means of getting it away from it all: YouTube.
