What is "costa-gavras"

Costa-Gavras (short for Konstantinos Gavras; Κωνσταντίνος Γαβράς; born 12 February 1933) is a Greek-French film director and producer, who lives and works in France. He is known for films with overt political themes, most famously the fast-paced thriller Z (1969), but he has also made comedies. Most of his movies have been made in French; however, six were made in English: Missing (1982), Hanna K. (1983), Betrayed (1988), Music Box (1989), Mad City (1997) and Amen. (2002). He produces most of his films himself, through his production company K.G. Productions.
