A group of people in Friesland (the Dutch province where the zombie outbreak takes place) were not amused by the film. They criticized how Friesland was depicted as a backwards rural area, and argued that the mindless zombies were a bad parody of Frisian people themselves. They also called upon cinemas in Friesland not to show the movie, and threatened to disrupt the premiere in Eindhoven. This didn't happen, but the town in Brabant used as the New Kids' hometown was later found to have been 'decorated' with Frisian flags and texts. Whether these actions were genuine or part of a secret marketing campaign has never been made clear.
Many of the extras playing zombies were fans of the New Kids on the Block (2007) TV show, and had responded to an open casting call via internet to be in the movie.
This is the second time that Huub Smit does full frontal nudity in the New Kids franchise. The first time was in one of the episodes of New Kids on the Block (2007) where he leaves the shower and directly walks outside. Although he never completely took off his clothes in New Kids Turbo (2010), there was one scene shot from the front showing him urinating.
Sylvia Hoeks, a fan of the New Kids on the Block (2007) TV show, had once indicated that she would love to play a part in the film, preferably as a low-life girl. She was offered a different role in the film, but she found it "too specific" and passed on the opportunity. She would later work with the same team on Bro's Before Ho's (2013).
