The film stars Bryan Brown, George Takei, Terry O'Quinn, John Bach, John Clarke, Deborah Kara Unger, John Polson, Nicholas Eadie, David Argue and Ray Barrett.

The film was the idea of Brian Williams, who was the son of Captain John Williams, who had prosecuted Japanese officers in charge of the POW camp at Ambon during the war. He was impressed with the TV series The Last Bastion and approached Denis Whitburn, who had written it with David Williamson, and they wrote the script and produced together. Bryan Brown and Stephen Wallace then came on board the project (although at one point Geoff Murphy was also considered as director).^[1]

The movie was shot at the Village-Warner Film Studio on the Gold Coast.^[1]

Blood Oath opened on 60 screens in Australia and grossed A$310,281 in its opening week finishing fourth place at the box office and went on to gross A$707,194 at the box office in Australia.^[2][3] Stephen Wallace has said he thought the film would have been better had the writers been more accurate as the truth was more interesting.^[4]

The writers announced plans to follow up Blood Oath with a $20 million film about the Cowra breakout, Giants at Dawn, but this was not made.^[5]
