Jacques Sernas (Lithuanian: Jurgis Šernas; sometimes credited as Jack Sernas; born 30 July 1925) is a Lithuanian-born French actor with an international film career. He was born in Kaunas, Lithuania, the son of Jokūbas Šernas, a signatory of the 1918 Act of Independence of Lithuania, who died when Sernas was a year old. His mother took him to Paris, France, where Sernas received his formal education. During World War II, he joined the French Resistance and was captured and interned at the Nazi Buchenwald concentration camp, near Weimar, Germany. Sernas worked first as a leading man and later as a character actor. He is perhaps best known for his role as Paris in the epic film Helen of Troy (1956). His more recent appearances have included appearing as a Cardinale Feltin in the television biographical film Pope John XXIII (2002) and as Ambasciatore in the television comedy film Regina dei fiori (2005).
