Note 1: Helge Hau has written and repeated in an undated letter entitled “Notes regarding. my personal relationships with cartoons.” The letter is from 1985. Henning Pade in a letter dated 20.3.1985. Also in the press it was mentioned that "Fyrtøjet" was originally supposed to be an only 10-minute cartoon. See the article "The first Danish Full-Night Cartoon", Politikens Tillæg Magasinet on ?.?. 1944.

Probably around the turn of the year 1945/46, Information under the heading "How "The Fyrtøjet" came to be" could tell in detail about the film's long and difficult creation. The undated clip also quotes from an interview with Allan Johnsen:

"- How do you get started with such a large task, we ask the soul of the company, director Allan Johnsen from Dansk Farve- og Tegnefilm", who has produced "Fyrtøjet".

- It really started with me writing a book called "Fra Dyreskind til Celluld", which was illustrated by the illustrator Finn Rosenberg Ammitsted. Both he and I were interested in film, and we came to discuss whether it was not possible to make a really good cartoon about one of Andersen's adventures here at home. We were aware that a short film could be of no use. With a movie like this, you have no way of getting your money back. No, it had to be one that lasted as long as a regular feature film. We chatted back and forth about the idea, and when Ammitsted wanted to take on the background of the film, I put myself in touch with the two literature students Peter Toubro and Henning Pade. And it ended up that, under Toubro's leadership, we started preparing a screenplay for "Fyrtøjet". It was completed in January 1942. "

The fact that the screenplay had been completed as early as January 1942 is probably a shift in memory on the part of Allan Johnsen, or a mistake on the part of the journalist, unless it is a printing error. January 1943 must be considered, as Allan Johnsen's book "Fra Dyreskind til Celleuld" was first published towards the end of October 1942. According to Henning Pade, Johnsen wrote his book during the summer of 1942, and Schønbergske Forlag mediated the connection with the illustrator Finn Rosenberg, who at that time was employed as an advertising designer at the advertising agency Monterossi.
