 This is a story that takes place against an international backdrop  so it was essential to find the right location, one that could  double for Europe, North Africa, Mexico, and Mayan Rainforest all in  one 50 mile radius. The filmmakers found such an area in Oklahoma.  The polarity of thriving cityscape of 1920s building design and  rural desolation served as the beginning of the whole world for the  "Rune" production. To further lend authenticity to the European  story the directors were making, lead actor Anna Bäumer was cast via  video auditions from Berlin, Germany.
