Across changing tastes and formats, Zoltán Mucsi has stayed a Hungarian actor recognizable to viewers well beyond any single title. Among the rest of the work, 'Kontroll' stands out. The first credits arrived long before the title most people know. Measured end to end, the working life on screen runs about 39 years. 'Tinker Tailor Soldier Spy' is the longest-standing point of contact with the audience.
