"It is summer and calm rests over the small town. But appearances are deceiving - in the idyll a war is being fought - between the White Rose (Kalle, Anders and Eva-Lotta) and the Red Rose (Sixten, Benke and Jonte). They are fighting for the Kingdom of Stormum, a completely ordinary stone for the uninitiated. Another thing that the uninitiated don't understand either, is the robber's language. During a critical mission, Eva-Lotta makes a horrific discovery. On the path in front of her, a figure looms, and when she looks closer, she recognizes the old man Gren - and he's stone dead! It's time for Master Detective Kalle Blomkvist to move out!There had previously been three films made about Kalle Blomkvist: Master Detective Blomkvist (1947), Master Detective and Rasmus (1953) and Master Detective Lives Dangerously (1957), on which the 1996 version is based. Director Göran Carmback had previously filmed Astrid Lindgren's stories Dearest Sister and No Thieves in the Forest. The ambition was to give the remake a modern but also timeless touch. The scenes in the small town were recorded in Norrtälje.Astrid Lindgren, who was 88 years old at the time, trusted SF: "I don't know much about the project, but it will certainly be nice," she greeted Aftonbladet. However, she had read the script and, among other things, demanded that the word "percentage", which had been replaced by a more modern word, should remain.
