Faithful to pure hyper-indie tradition, the director sold his house and most of his belongings to pay for this first film, and faithful to the same tradition ... has remained bankrupt since.
The shooting of the film having taken nearly a year, and the boy actor going through the same changes as in the film, some latter scenes had to be 'tweaked' in the audio post-production to bring his voice up one semitone without changing the speed. Changes in his voice were unnoticeable in real life, but very much so at time of edit.
Shooting took one year, as the director explains, in order to shoot the changing seasons and countryside, that reflect the mood and thoughts of the protagonists.
