On Kenneth's passport above the photo there is a headline called "Sichtvormerke" (spelled incorrectly). This headline is on the wrong page of the passport because in real passports the pages marked "Sichtvermerke" contain the stamps when you enter a foreign country, not the persons details.
At 17:20 we see a close up of Kenneth's passport. His photo is tied to the passport with a seal reading Germany. While a German passport would use the German name for the country, Deutschland, the page of the passport shown does not include the name of the issuing country (as well as height) at all.
