There was no production vehicle, so the crew carried all the gear to the locations, often walking over 10 kilometers per day.
The writers (who also make up the main production team) do not speak Norwegian. They wrote the script in English and had it translated for the actors. Extensive rehearsals were done to achieve the right mood and performances. In post production, every take had to be translated back to English and subtitled so that the film could be edited.
The film was completely independently funded.
The on-set crew was just 5 people, sometimes less.
Shot in just 13 days.
