Well I found the original news report of Greg Shackleton, which the movies copies word for word! http://www.youtube.com/watch?v=ojS0B2WRS3o&feature=related
I am also still reading shooting balibo by Tony Maniaty, a journalist who knew the Balibo 5 and Roger East, so far it is more of his emotional experiences and linking present Dili to the one in his past. He also describes the research done not only by the movie directors but by the actors, he says that cast have files on the background of every character in the film. His account of the movie set is clear admiration for their thoroughness in research of East Timor around 1975.
