In late 2004, many months before this film was released to the public in August 2005, US Ambassador to the Philippines Frank Ricciardone contacted Miramax producers Harvey and Bob Weinstein, with whom he was acquainted, to request a personal favor. Ambassador Ricciardone asked if the Weinsteins would consent to allow the U.S. Embassy in Manila to hold special screenings of this film during the Embassy's celebration of the 60th anniversary of the Cabanatuan raid. Remarkably, the Weinsteins gave their blessing for the U.S. Embassy to make limited use of the film, an act that had no precedent. Thus, during February 2005, seven months before its public release, the film was screened for a limited audience of both American and Filipino employees of the U.S. Embassy, plus some family members, as well as a select group of people involved in the movie's production (Director John Dahl was present), the Hampton Sides novel that provided some of the film's material (Mr. Sides was present), and the 60th anniversary ceremonies at Cabanatuan. The film was screened at a theater in the Greenbelt 3 Mall at Ayala Center in Makati - the main financial and entertainment district of Manila.

Originally set for a US theatrical release in 2003 and then in 2004; the film was then pushed back indefinitely by Miramax. Two massive waves of layoffs were sustained at the studio, and the Disney-Miramax split reached its height. The movie remained in the Miramax vaults unreleased during this time of uncertainty. When the Disney and Miramax divorce was finally completed, numerous films like this one under the Miramax and Dimension label were finally released theatrically.
