Sebastien Sisak

Sebastien Sisak (also credited as Себастьян Сисак and 세바스티안 시삭) is an Armenian-born screen actor known for a rare, real-world path into performance. Born in Yerevan in 1981, he grew up in a Russian-language school environment and later built a foundation of discipline through martial arts, training in karate for a decade and earning a black belt, along with multiple national titles in Armenia.

Before acting, Sisak pursued law and criminal investigation, graduating from the Armenian Ministry of Interior’s higher school with an advanced degree in penal law. He served in policing roles that included criminal investigation work, distinguishing himself for precision and composure—skills reinforced by top marks in firearms training. After leaving the force, he relocated to France, completing university studies and spending nearly a decade in legal practice across Aubagne, Nice, and Paris.

In 2008, Sisak began performing on stage in Nice, moving from French theatre into screen work as his range expanded. He later trained in Paris in the American Meisner technique and continued sharpening his craft in the UK with respected coaches connected to Drama Centre and LAMDA.

Fully dedicated to acting since 2012, he has appeared in international productions including Guardians (as Ler/Lernik), The Earthquake, Petropolis, Artek: Through the Centuries, Unforgiven, and The Last Trial.
