Sylvester Stallone takes on the Cold War in this fourth Rocky installment, as the titular hero must come out of retirement to battle a gargantuan Soviet fighter named Drago (Dolph Lundgren), who brutally punished Rocky's friend and former rival, Apollo Creed (Carl Weathers). Seeking revenge in the name of his fallen comrade and his country, Rocky agrees to fight Drago in Moscow on Christmas, and the bout changes both fighters -- and the world.
