Jessica Chastain is on the kind of run that most actresses would dream of, and is actually in a position that she can turn down blockbusters - which she just did with Iron Man 3. She was also due to play Princess Diana in a biopic of the much loved British icon, but had to be replaced with Naomi Watts when she was too busy to officially commit. We'll next see her in The Hurt Locker director Kathryn Bigelow's Osama Bin Laden hunting flick, Zero Dark Thirty.

"I think with any movie when you're telling a story like we're telling, there's an insane amount of pressure," Chastain told The Hollywood Reporter, "because you want to honour the people that really were there, and you want to honour history." She added, "We shot a lot of Chandigarh, India, which is near the border of Pakistan, and it was a long shoot, it was a lot of stress. But I will say it was one of the best scripts I've ever read, the part is phenomenal, and the company that I'm in that film, it's wonderful." The film also stars rising Aussie actor, Joel Edgerton, Jennifer Ehle, Chris Pratt and Mark Duplass and was written by The Hurt Locker scribe Mark Boal.

The film is scheduled for release in the US in December, with no Irish release date set as of yet.
