The song "Where's The Real Sky" is credited to Jeff Cole on the soundtrack and was mentioned in the movie as a favorite artist of Jan and Jule. Jeff Cole is a pseudonym for the score-writer, Andreas Wodraschke. The singer is his friend Sam Genders of London.
The tagline in the English-language releases of the film, "Your days of plenty are numbered", is a direct translation of the film's original German title.
