The subject of this graduate thesis is a comparison of cartoon animated films Petar Pan (1953), Petar Pan (2002) and movies Kuka (1991), Petar Pan (2003), Pan (2015) with Peter Pan James Matthew Barrie's book. The aim of the paper is to determine the importance of Barrie's stories in the context of children's literature, the ways in which it is transferred to the film medium and the justification for incorporating this story and film adaptations into elementary school. The paper will present a book and a writer in the context of children's literature, as well as the impact and experience of a story that is left to readers. In this paper, each of these movies will be compared with the above-mentioned book and the similarities and differences of the fable, characters and events will be analyzed, and childhood sufficiency will be determined and the original idea of the writer will be well transferred to the film medium. When analyzing the movie, there is also mentioned the presence of film-making materials (color and sound) that create the atmosphere of watching the film, as well as reviews and criticisms of the film. There is also a resume of writer James Matthew Barrie and biographical drama San za životom (2004), which shows the relationship and specific connection between characters in the film and James Matthew Barrie, who have just led to the emergence of his most famous work. The play Petar Pan (1904) was also mentioned, which was the basis for the creation of a complete story and a book that was later printed. In this paper, it is proved that the literary work is as important as the film adaptation of the work and how the film and the book can be offered to students, depending on their preferences.
