Buddha's Lost Children shows how Khru Bah, a Thai kickboxing champion turned monk, has become an unorthodox father figure for many orphaned or impoverished children from villages in rural Thailand. Filmed over the course of a year, fly-on-the-wall style, it reveals that although some of Khru Bah’s physical childrearing methods may seem unorthodox, he clearly has won the affection and respect of the villagers and his children.

The mountainous setting for the monastery, with its stables of ponies and lush landscape, and a long trek made by the new boys, or "novices", is evocatively shot, but the film could have been more circumspect. For example, Khru Bahas training as a monk is skimped over and there's little sign of any drugs that we are repeatedly told are such a prevalent problem in the region.
