Jessica Chastain Felt The Pressure Filming 'Zero Dark Thirty'

Like the confidential missions the movie is said to explore, "Zero Dark Thirty" has kept more than a few of its details well-protected secrets. Little is known about the upcoming Kathryn Bigelow movie aside from that it will retell at least part of the manhunt for Osama Bin Laden.

MTV News' Josh Horowitz spoke with one of the film's many stars, Jessica Chastain, about her role in the mysterious project and how filming such sensitive material affected the shoot.

Handling a topic as delicate and secretive as the hunt for Bin Laden is bound to come with some extra pressure, but shooting "Zero Dark Thirty" near where the actual events took place added a whole other layer of stress for the cast and crew.

"It was a very stressful shoot. Maybe that's all I should say," Chastain said. "It was a very stressful shoot, but how could it not be when you're dealing with that kind of material and you're in that part of the world. We were shooting part of it in Chandigarh, India, which is on the border of Pakistan."

Chastain hesitantly admitted that most, if not all, of the cast is playing real-life characters, which also complicates retelling their story. "It's such great responsibility in the story we were telling," she said. "It was a lot of pressure. I think the script is one of the best scripts that I have ever read, and my part is awesome. I'm excited for it to come out at the end of the year."
