Just after the German release, a review authored by "Kino Kritik - Arthaus", which satirized the movie, started a big debate on whether it is tolerable to approach family friendly material in that way.
The name of Matthias Schweighöfer's character "Clemens Klina" is obviously a play on Orson Welles' "Charles (Foster) Kane" from Citizen Kane.
Filmed on the same Isle like Connie & Co 2.
