Rocky IV features Rocky Balboa fighting Ivan Drago in Moscow. Released in 1985, the film presents the bout as a highly publicized confrontation between Rocky and the powerful Soviet boxer.
The story begins when Apollo Creed challenges Drago to an exhibition match in the United States. Drago's brutal punches fatally injure Apollo, prompting Rocky to accept a fight against Drago. Rocky trains in remote Siberian surroundings while Drago prepares with advanced equipment and scientific support.
The final bout takes place in Moscow on Christmas Day. Rocky survives Drago's strength and eventually wins by knockout. The film uses the contest as both a personal revenge story and a Cold War-era sports spectacle.
Dolph Lundgren played Drago, while Carl Weathers returned as Apollo Creed. Rocky IV became the highest-grossing installment of the original Rocky series and later led to the spin-off film Creed II.
