worker, gromo alex. who is he and let's show that one. someone is being macheted but it is at a great distance. >> he is a guy from a small town in pennsylvania who was a football player in high school and college who wanted to be a hero. he went off seeking adventure and he worked with u.n. relief agencies and ended up in rwanda working for the u.n. before the genocide began. there was a big u.n. peacekeeping operation there. he found himself tested during the genocide on a deep, personal level. he was my first way into the whole story. when i got to rwanda, i had a gut feeling that there were people who did amazing things and their stories had not been told. i was asking around and saying, was there anyone from the u.n. who was here at the time and is still around? finally someone told me about gromo. that guy is a hero. i went to see him and he was still there. i said, i hear that you are a hero. he said, no, i am not, but i knew a guy who was. and he started tearing up. the true hero that he wanted to be was a single lease peacekeeper

>> because in the course of doing the rwanda film, i met people like gromo alex. the best and brightest of the u.n. -- whatever you think about the un, a lot of good people work there. i became interested in this guy possible light. samantha power's, who was at harvard at the time, was someone i met through the rwanda them, and she had met searching. >> and she works for president obama. judith it was a way to speak to a lot of issues on a personal level, and i saw an amazing story. the film is basically a search and rescue movie about what happens after sergio is headed the un mission in iraq, after that the first big terrorist attack and war, he is trapped in the rubble with another guy after his building has collapsed. these two amazing american soldiers try to get him out. it's a way of telling the story for a broader audience. i was appointed my career for as much as i loved my job at front line and pbs, i wanted it to longer films. this was a story that hit me on a lot of different levels. >> when did sergio die? >> august 2003. >> did he die in the rubble?
