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.
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.
Inger Nilsson was selected out of 8,000 actresses auditioning for the role. Director Olle Hellbom had realized he found his Pippi once he saw Inger skipping through the door at the beginning of the final B&W screen test. He said of Inger, "All the others had only dressed up as Pippi, but this Inger had that extra something. She had Pippi on the inside."
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.
