Vasilis Diamantopoulos was a distinguished Greek actor, director, and teacher whose presence shaped postwar Greek theatre and screen performance. Trained at the Drama Schools of the National Theatre and the Art Theatre of Karolos Koun, he co-founded the New Theatre in 1956 with Maria Alkeou and later established the Modern Theatre in 1993, contributing decisively to the development of contemporary stage practice in Greece. In 1966 he became the first actor to appear live on Greek television in the one-act play 'Aftos kai to panteloni' tou by Iakovos Kabanellis. On film, he is widely remembered as the strict ancient Greek teacher in Nomos 4000 (1962), directed by Giannis Dalianidis, a role that became emblematic of authority figures in Greek cinema. He also reached new audiences through television, notably with the series Ekmek pagoto (1991). Alongside his extensive work in theatre, film, and television, he taught acting at the National Theatre and the Art Theatre schools and founded the higher drama school Iasmos, leaving a lasting legacy as both performer and mentor.
