The authorial project "One odlaze" was created as the graduation performance of Mateja Tustanovski and Iva Slavić, under the mentorship of Assistant Professor Anica Tomić and comentorship of Assistant Professor Jelena Kovačić. The work on this performance is the practical part of the final exam for Iva Slavić, a student of the master's program in acting at the Academy of Arts and Culture in Osijek. In her thesis "Work on the role of Iva in the play One odlaze", Slavić touches on all the developmental phases. From the initial idea conceived between her and her colleague Tustanovski for writing their original piece, to the initial phase of writing the text and its gradual development towards the stage production of the play and the creation of the role. Here, Slavić presents her observations during the work on the text in a scientific-artistic manner, shares her thoughts, and experiences of her personal insights. She further introduces us to the research development of the role she plays in the performance. Additionally, this thesis includes numerous reflections on what acting is and what it could be. Slavić shares her personal methods used in creating the role and gives us a better understanding of her own preparation process for rehearsals and the exam itself. The practical part of this exam began in February 2024 and lasted until the exam on June 5th of the same year. The work on this graduation performance was unique and very intense, providing an opportunity for interesting, authentic, focused, and dedicated work on building the performance and the roles within it.
