The monkey playing Mr. Nilsson behaved violently on occasion, and was hated by the entire crew. It bit an electrician's hand, and peed on Inger Nilsson, who played Pippi.
The house used for Villa Villekulla was located in Vibble in Gotland, Sweden. Since early-to-mid 1970, the house was sold, and the garden was taken out. Thus, its last regular appearance would be in the film Pippi in the South Seas (1970). In the next (and last) film, Pippi on the Run (1970), the house, still used, could not be fully seen (it was in the process of being transported), and was placed in two noticeably different locations: on a grassy hill by the sea (early in the film), and an open field in a forest (a little later in two scenes, when the house was last shown), and both locations had no fence like the original; full exterior shots were done with a miniature model. The house had been transported to Kneippbyns Summerland in Gotland (just three kilometers away from its original location in Vibble), where it stands to this day, and has become a popular tourist attraction. Meanwhile, the original garden spot where Villa Villekulla was once situated can be seen when visiting Toftavägen. A scots pine tree has grown on the spot where the house originally stood.
A book about the production of the series revealed that Margot Trooger, who played Ms. Prysselius, was not always sober when acting.
Although this series was filmed in color, it was originally broadcast in B&W, as Sweden did not broadcast color television until April 1, 1970.
The exterior of Villa Villekulla (Pippi's house) is a house located in Gotland (see another trivia entry in this section for more information about the house), whereas the house's actual on-screen interior was in a big soundstage at Svensk Filmindustri in Stockholm. The cast of the series appearing in and out of the house (particularly Inger Nilsson as Pippi, Pär Sundberg as Tommy, and Maria Persson as Annika, as well as the animals playing Mr. Nilsson and Lilla Gubben) would be flown from Gotland to Stockholm and back again for all exterior/interior shots.
