The series ended when Coen van Vrijberghe de Coningh, who played Johnnie Flodder, died of cardiac arrest while performing with the other Flodder actors at a corporate party - just three days after principal photography had wrapped.
Both Huub Stapel (Johnnie) and René van 't Hof (son Kees) did not want to reprise their movie roles in the television series, so their parts were re-cast with Coen van Vrijberghe de Coningh and Stefan de Walle. This also caused an abrupt personality change in both characters. Johnnie had been a shady and untouchable macho in the movies, but van Vrijberghe de Coningh decided to portray him more as a fast-talking hustler who often falls vicitm to his own big mouth; Kees had always been portrayed as a wimpy loser, but he was re-invented as a childish and good-natured idiot for the series.
No-one is ever seen actually swimming in the pool in the Flodders garden. This is because the pool was built in the First Floor Features studios and therefore was only several centimeters deep.
The series took the premise of the first Flodder (1986) movie, but basically ignored the continuity of the first two films. For example, the family's grandfather is alive again after dying in the first movie; Sjakie (Lou Landré) does not seem to have undergone his accidental transgender surgery from the second movie; and the neighbors, Clarissa and Arie Neuteboom (Lettie Oosthoek and Bert André) are now called Tilly and Ed. The dynamic between brothers Johnnie and Kees in the movies (where the former was a surrogate father of sorts for the latter) was re-imagined as a more comedic Laurel & Hardy-type relation for the series.
Several of the actors speak in very different working class accents while portraying members of the Flodder family. Coen van Vrijberghe de Coningh speaks in a thick Amsterdam accent, while Stefan de Walle uses the typical working class accent from The Hague. Tatjana Simic speaks with a very thick Rotterdam accent in the first movie, which was toned down in the series. The differences could be explained because it's mentioned on several occasions that the Flodder children all have a different father.
