In adapting the book, Bolognesi considered the work as his inspiration but felt free to create situations or characters and to modify the personality of the characters. Carrano accepted Bodanzky and Bolognesi's offer as they stated that their wish was to keep the base of the story while adapting it when necessary for the general public or to keep the efficacy of cinematic storytelling. Bolognesi wrote Neto as a shyer character than Carrano did, and made him not the leader of the class but a common student. His objective was to create a character that would reflect the regular viewer rather than "a hero." He also softened some scenes and removed others that he thought the public would find unbelievable.
