Only animated feature to be produced entirely in Thailand until The Blue Elephant (2006) and The Life of Buddha (2007).
When production started in 1976, one hundred crew members participated. However, as it entered its second year, the figure dwindled to just nine.
The film's intensive production, along with excessive exposure from light, caused director Payut Ngaokrachang's eyesight to be impaired during production.
Surplus materials from World War II military personnel were used by director
Payut Ngaokrachang for this film's camera equipment.
