The Character Died with Him: The franchise was finally put to an end when actor Coen van Vrijberghe de Coningh suddenly died from a cardiac arrest.
I Am Not Spock: Nelly Frijda, who played Ma Flodder in the entire franchise, openly stated that she hated the fact that people now mostly remember her as this character.
The Other Darrin: Sjakie, Ma Flodder and the female Kees are the only main characters that are played by the same actors in all movies and the entire series. The roles of Johnnie and the male Kees were played by Huub Stapel and René van 't Hof respectively in the first two movies, but since both actors quit afterwards, Coen van Vrijberghe de Coningh and Stefan de Walle took over for the third movie and the TV series. Granddad Flodder was played by Jan Willem Hees in the first movie, and Herman Passchier in the third movie and TV series. The roles of Toet and Henkie have both been played by four different child actors in order to keep these characters at the same age.
