Set dressings were researched from photographs and WWII veterans and obtained from a variety of sources, including the ABC prop store, other Sydney prop houses, private collections, auctions, and second hand stores.
Two of the older cast served in WW2. Charles 'Bud' Tingwell was a fighter pilot and Slim DeGrey as a stretcher bearer. Slim DeGrey was an POW at Changi after the fall of Singapore. DeGrey wrote a book about it, recording the history of the theater group that was started inside the camp. It's called "Changi, the funny side"
A total of 53 sets and locations had to be made and dressed including the prison barracks and a Malayan jungle. Just finding a site big enough to hold the main set of three 8 meter high buildings, which could pass for Singapore was laborious.
