The Strange Adventures of Hlapich the Apprentice was first published in the year of 1913. Ivana Brlić-Mauranić tried her best to create a character that would be the embodiment of kindness. Her book is one of the rare works of child literature that has a couple of film adaptations. The first try of a movie adaptation, unfortunately unrealized, was in 1965. when Ivan Brajdić and Zorislav Ugljen adapted the novel into a script. The unrealized adaptation was followed by the two successful ones. The first one was an animated feature film by Milan Blažeković in 1997., followed by a feature film by Silvije Petranović in 2013. Every one of these versions has their characteristics and specific adjustments to the adapting media. This literary work abounds with vague places that the film must fulfill because it is a visual art, especially the physical appearance of the character, things, relations between them and so on. The animated film is specific because of anthropomorphic animal characters. Present day generations imagine a mouse at the mention of Hlapich, because Hlapich the mouse“ became a brand and it can't go unnoticed, On the other hand the feature film follows the action of the novel the closest, although the film takes the place between the two wars. Although he tried to stay true to the original book script, Petranović introduced his version to it. We can find the biggest digression from the literary work in the unpublished script. Brajdić and Ugljen had their vision of space, characters and the action of the movie. Who knows what kind of perception of Hlapich we would have today if their script had been realized.
