When Donnersberg returns from New York to Berlin, in the office he wears a gray tie; in the political meeting in the next scene he wears a green tie.
The real-life town Kulbach, Bavaria is replaced by the fictitious town Donnersberg, which itself is not a goof. In 2002 and 2005 Kulmbach/Donnersberg was election district 241. However, the voting ballet for the German federal election 2002 is made for election district 240, credited for Donnersberg. But in in 2002, and in 2005, election district 240 was reserved for Hof, Thuringia, not for Kulmbach. It became district 240 only for federal election 2009.
In one of the newspapers the name Franz-Ferdinand is misspelled as "Franz-Ferdinant"
The format of the "Blitzkurier"-newspapers from 17 February and 23 February are exactly the same; it's visible that the sports results and the weather reports are exactly the same. Only the main headline about Donnersberg is different.
There is a microphone from 2002 in a press in Berlin in 2009. It has the logos of the German TV channels N24 and Sat.1, which were different in 2009.
During the love-parade scene set in 2000, Franz Ferdinand and Max quote the line "Berlin is poor but sexy", a reference the quote "Look at Berlin, we may be poor but we are still sexy" by Berlin's mayor Klaus Wowereit. This line was said and popularized as "Poor but sexy" in 2003.
On one newspaper the data is Monday, 17 February 2011; 17 February 2011 was actually a Thursday.
The scenes in New York are supposed to take place in 2009, but on the Broadway shot a marquee for the musical "Newsies" (which premiered in September 2011) is visible.
In the meeting with Franz Ferdinand, Max and Jan Breitmann, Breitmann calls Max "Moritz" without being interrupted. This is clearly made to show Breitmann's superiority and disrespect to Max. The name Moritz is here a reference to the book "Max and Moritz" by Wilhelm Busch.
