This documentary movie took over 10 years to make and spanned 3 continents as the filmmakers were primarily based in Barcelona, Spain yet filmed in Thailand and the USA.
Various sequences were filmed in the Kayan language and translated afterwards with the help of other villagers. Often times, the filmmakers would discover the weight and intricacies of the conversations days, if not weeks, later.
The Kayan families seen in this film have been resettled all over the U.S., as well as Finland, Australia and New Zealand.
