When Thomas takes part in the quiz show, one of the possible answers given for the Germans' "absolute dream woman" is actress Veronica Ferres, who actually plays Thomas's wife in this film.
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.
