This work is meant to contribute to the research of adaptation studies by focusing on a special case: the transformation of a fictional diary into a movie. In order to sustain the form of the literary source the adaptation to movie requires certain strategies. Först of all, the diary genre is characterized by a one-dimensional narration. Second, diaries only supply a few written dialogues, hence this "void" has to be compensated and filled by media specific measures. Third, the investigated diary is a story of individualization and emancipation of a single woman. Therefore not only the lack of dialogues but also the lack of actors composes a challenge to the work of adaptation. The main task is thus to analyze the literary source and the movie and identify the specific strategies that make the transformation of a fictional diary to a movie possible.
