Transcript for 'Zero Dark Thirty' Focuses on Young Female CIA Agent
And finally tonight a new story of incredible determination. It's been a year and a half since the death of osama bin laden, and we now know that a young woman was a key to it all. She's even at the c of a new movie and here's abc's senior affairs correspondent martha raddatz. Reporter: It is the story everyone thinks they know. The stealthy nighttime raid by the elite s.E.A.L. Team 6 sweeping into the bin laden compound in pakistan. You arethe elements. You are in the wind. You are in the sand. The sound of the rotor wash and you can't see anything. Reporter: "Zero dark thirty" has it all, but the oscar-winning team behind "the hurt locker" focused on a stunning new twist in the bin laden story. At the center of this decade-long manhunt, a tough, young female cia officer played in the movie by jessica chastain. I didn't even want to use you guys. I wanted to drop the bomb. I was blown away when i realized at the heart of this was this young woman who had a kind of tenacity and a dedication and a courage she would never say no. You're going to kill him for me. Reporter: It was maya as she was called, who was convinced that tracking a long-forgotten bin laden courier would lead them to the terrorist himself. You are -- you got him? Reporter: I'm cure house. At what point she knew she would be the focus of the movie. Well, I think that a lot of people that I spoke to -- and i think she was included in this -- were in an unusual position where they were proud of what they had done, but they had more or less resigned themselves to the fact that what they had done is not something they could talk about publically. Reporter: For one very good reason, hollywood movie or not, many of the real stars of this film like maya are likely back at work back in the shadows. Martha raddatz, abc news, los angeles.
