Being huge fans of the 80s TV show "The Tripods" by the BBC, the filmmakers hid the title melody from that show in the waveform of an emergency signal in the film.
The blue drug that protagonist Tomasz is taking, is actually blue nail polish dye. The actor Stefan Ebel wasn't supposed to really take it but he did so anyway.
Only two lines are spoken by the actors in the whole film. One in English by Tomasz (Stefan Ebel) and the other one in Russian by Lilja (Siri Nase). Both are saying the words "I am here!" in their languages.
The whole film was financed via a crowdfunding campaign on Kickstarter by Daniel Raboldt and Thorsten Franzen. Almost everybody worked for free on this film, but got paid after the release of the film.
Most of the film was shot in Finland, north of the arctic circle during the period of the Midnight Sun. For the night scenes the crew added additional shooting days in Germany because it was never dark enough in Finland.
