While the quiz show in the film, "König von Deutschland", is fictitious, it contains elements of real quiz shows on German TV, including Wer wird Millionär? (1999) and Familien-Duell (1992) . When asked "Name something which is beaten", the female participant says "A child" - an exact dialogue from a real episode of Familien-Duell, which is included in various lists and YouTube videos of the most unusual answers from German TV quizzes.
In the quiz show, the name of singer Wolfgang Petry is misspelled as "Wofgang Petri". There are also other spelling errors within the questions and answers; for example, "sie" is always written with a lower-case s, while it is still written with an upper-case S when used as an addressing pronoun.
