Curiosidades

Production on the series was shut down before all 13 planned episodes were filmed because director Paul Verhoeven went over budget. It was decided to split one episode, "De Byzantijnse beker" into two parts because there was enough footage, while two other stories remained unfinished. The thirteenth spot in the broadcast schedule was filled with the documentary Rond Floris (1969). Despite of this, Gerard Soeteman had already completed some scripts for a proposed second series, which ended up being adapted as a newspaper strip by Gerit Stapel, and some of them ended up being filmed for the German remake, Floris von Rosemund (1975).

In one episode, Rutger Hauer dislocated his shoulder jumping from a castle into a moat. During the filming of Los señores del acero (1985), writer and director Paul Verhoeven was astounded by Hauer's refusal to do any stunts.

Carol van Herwijnen was director Paul Verhoeven's first choice to play Floris. He could not take the role because of his commitment to a Rotterdam acting company, but did play a small role in De drie narren (1969).

At the time, this was the most expensive Dutch television show ever made, with an estimated budget of one million two hundred thousand guilders, which is about five hundred forty thousand Euros, and extraordinary production values with sometimes more than two thousand extras.

The "lost" episode thirteen, "Het Gericht", which was only partially completed, was released at Castle Doornenburg nearby the Linge on August 19. 2016 in a reconstructed form combining the remaining footage with images from the 1972 newspaper strip.
