Istanbouli’s journey began in the southern city of Tyre through politically and socially critical plays, defying traditional norms. He successfully broke into public squares and streets with a team performing mobile shows while he was still in his second year at the Lebanese University’s Institute of Fine Arts. The turning point in Istanbouli’s life came in 2014 when he reopened the "Colisée Cinema" on Hamra Street, which houses a theater stage that had been neglected for decades.
