Rocky IV

Sylvester Stallone decided that for the shooting of the fight, he and Dolph Lundgren should hit one another for real, so as to increase the intensity of the scene. After doing three takes of Rocky taking shots to ribs, Stallone felt a burning in his chest, but ignored it. Later that night, he had difficulty breathing and was taken to a nearby emergency room. It was discovered that his blood pressure was over 200, and he had to be flown on a low-altitude flight from Canada to St. John's Hospital in Santa Monica, where he remained in intensive care for four days. What had happened was that Lundgren had punched him so hard in the chest, Stallone's heart had slammed up against his breastbone and began to swell, cutting off the blood supply and restricting the oxygen flow throughout the body. . However, when asked about whether or not it really happened while answering a series of fan questions in a 2021 interview with the Guardian, Lundgren claimed to have no recollection of the incident. "I don't know," he said. "[Stallone] keeps talking about it, so maybe he's right. He did go to the hospital, but I don't know whether it was my punches or the fact that he was so overworked as the director, actor and writer. We shot those 15 rounds over two or three weeks, eight or 12 hours a day, so you're throwing thousands of punches. If you don't connect, it looks a bit fake, but it doesn't mean you want to hurt the other guy. But there were no hard feelings." He went on to explain that stand-ins and stunt doubles were rarely used, and that he has performed the majority of his own stunts and fight scenes--but that this has changed in more recent years. "Back in the day, you had to do it all yourself: Rocky IV, The Punisher, Masters of the Universe, all the Expendables," he said. "I've jumped from a motorcycle to a truck; dangerous things I would never do now. Staying physically fit over the years has been nice. There aren't many actors who can stay physically fit for a long time. Part of the game is trying to look fit, at least."

At the end of the Drago/Rocky Bout... Rocky gives a speech where he says, "Today there are 2 people killing each other but I guess it's better than 20 Million people". The Russian translator however translates this as "It's better than 20 Million Dollars". (Theatrical cut only, as the "dollar" mistake was cut out of the director's cut)
