Familiar, disturbing images from five years ago flash by in 9/11: Press for Truth." But the 86-minute documentary, directed by Ray Nowosielski of Indianapolis, also asks what warnings top government officials received before the terrorist attacks, and why so many questions remain unanswered. The limited-run movie, opening in 27 cities, premieres tonight in Manhattan. It will show in Indianapolis Friday through Monday. Nowosielski, 25, and co-producer John Duffy got the idea for the movie in 2003, during their last semester of film school at Columbia College Chicago. It was there they learned of Paul Thompson's "The Complete 9/11 Timeline," and went online to read the researcher's compilation detailing the events surrounding that fateful day. "We ended up reading until the sun came up," said Nowosielski, who recently opened a Massachusetts Avenue office. Nowosielski said he double-checked whatever they used. "We did everything we could" to ensure accuracy. The documentary prominently features Thompson; Bob McIlvaine, whose son died in the World Trade Center attack; and several 9/11 widows who became known as "the Jersey Girls." McIlvaine, after screening a rough version of the film, sent Nowosielski an e-mail signed "Forever grateful," thanking the filmmakers and saying, "Every high school, college and university should have a copy of this documentary."
