Michail Gorbatchev

As General Secretary of the Soviet Union, Gorbachev presides over the Kremlin's response to Chernobyl from behind a long table, pressing his officials for a clear picture of the disaster. He is measured, impatient with evasion, and wants facts rather than reassurance — a leader trying to govern a catastrophe no one around him wants to fully describe.

Dencik plays him with a stillness that makes the surrounding panic legible: every flicker of irritation or doubt on his face registers as a crack in the state's confidence. The writing uses him less as a personality than as a pressure gauge, and Dencik's restraint makes that function feel like a real, watchful man.
