Rocky IV - Production

Production

Wyoming doubled for the frozen expanse of the Soviet Union. The small farm where Rocky lived and trained was in Jackson Hole, and the Grand Teton National Park was used for filming many of the outdoor sequences in Russia. The PNE Agrodome at Hastings Park in Vancouver, British Columbia, served as the location of Rocky's Soviet bout.

Sylvester Stallone has stated that the original punching scenes filmed between him and Dolph Lundgren in the first portion of the fight are completely authentic. Stallone wanted to capture a realistic scene and Lundgren agreed that they would engage in legitimate sparring. One particularly forceful Lundgren punch to Stallone's chest slammed his heart against his breastbone, causing the heart to swell and his breathing to become laboured. Stallone, suffering from laboured breathing and a blood pressure over 200, was flown from the set in Canada to St. John's Hospital in Santa Monica and was forced into intensive care for eight days. Stallone later commented that he believed Lundgren had the athletic ability and talent to fight in the professional heavyweight division of boxing. The punch was so hard the hospital initially thought he had been hit by a car.

Additionally, Stallone claimed that Lundgren nearly forced Carl Weathers to quit in the middle of filming the Apollo versus Drago "exhibition" fight. In one take for the Creed-Drago fight scene, Lundgren tossed Weathers into the corner of the boxing ring. Weathers shouted profanities at Lundgren while leaving the ring and announcing that he was quitting the movie and calling his agent. Only after Stallone forced the two actors to reconcile did the movie continue. This event caused a four day work stoppage while Weathers was talked back into the part and Lundgren had to be forced into toning down his aggressiveness.
