Boris Liješević is a three-time scholarship holder of the Goethe Institute in Belgrade, and a member of the Zagreb Acting Studio, where he teaches the Strasberg Method.
Many of his works focus on documentary theater, where the author's projects are created by recording thematic conversations with selected anonymous interlocutors who reveal their authentic experiences: " Waiting Room" and "Fertile Days", "In Commemoration of the Seagull", "Our Fathers Were the City (Builders)", and "The Fifth Park".
Based on classical works Liješević staged Carlo Goldoni's comedy "The Servant of Two Masters", Euripides' "Alcestis", Alfred de Musset's "Lorenzaccio". Isidora Žebeljan's opera Two Heads and a Girl, based on a libretto by Borislav Čičovački, which he worked on in 2016, represents his first experience in opera directing; he was the supervising director of M. Živkovič's children's opera The Children's Room, based on poems by M. Zivkovic. The basis of his directing work is staging novels.
