The series was filmed around old black and white footage. After 1 episode was broadcast, a woman recognized black and white footage of her husband from 1940 and had been killed soon after, that was used in the episode and it was the 1st time the woman's children had seen their father.
Actors involved in the storyline set in Singapore's Changi Prison undertook a three-week course in authentic prisoner behavior and were taught some Malay. The shoot actually took place in a gasworks during the cold Melbournian winter, a hardship for castmembers in sarongs and heavy suntan make-up.
The first Australian series to run continually for more than 7 years overseas.
