A novel by Werner Meier was published in German in Austria in 1987 which retells the story of the TV series with almost no differences.

Unlike in the novel, Aunt Hannah meets more spooks like a merman, a fire spirit and a White Lady and the orphan Max, who is running away from a circus.

Beyond their intent to entertain, their goal was to emphasize the triumph of reason and sanity over human aggression and intolerance.

[2] The series was an international co-production from: Filming location were Hallstatt, the environ of Salzburg, Dachstein, Boskovice and Werfen with Burg Hohenwerfen.

[3] Jacques Herlin, who played Igor, said in an interview,[4] that the filming was a lot of fun, the only bad side being Viveca Lindfors who hated the director from the first day.

The character of the "White Lady" (played by Mercedes Sampietro) was inspired in Elizabeth Bathory[5][better source needed](1560–1614).
