Gerard Cox and Joke Bruijs have been married in real life.
In the original TV sitcom, Coby Timp played the role of Svetlana van den Broek, Henk van den Berg's hard-hearing landlady. For the movie spin-off, Timp took the role of Nel's mother, who had been played by Elisabeth Versluys in the series, but passed away in 2011.
Since the movie was shot on location instead of a studio set, several locations could be shown which were never seen in the original television show. These are the garage, the sewers (including the office of the Bruine Rotterdammer newspaper) and the house of Jaap's mother-in-law. It's also the first time that Jaap and his colleagues are seen driving a bus. The house of the Stokvis family had appeared before, but only a few times in the first 3 seasons.
All locations from the original TV series look very different, due to the movie being shot on location instead of a studio. Instead of the Kooiman and Stokvis families living above the laundry, the laundry is set on the other side of the street.
The TV show often mentioned Nel's father, who almost never appeared due to a bad leg. Although the movie show's the apartment of Nel's mother, her husband is never mentioned, as if she is a widow.
