Whereas filming Rocky IV, Sylvester Stallone gave Dolph Lundgren “orders to attempt to knock [him] out whereas the cameras had been rolling.” He stated, “At one level, he hit me so onerous on the highest of the pinnacle I felt my backbone compress. He then hit me with an almighty uppercut. That evening, my chest and coronary heart began to swell, and I needed to be helicopter-ambulanced from my lodge to a close-by emergency room. I used to be advised that Dolph had punched my rib cage into my chest, compressing my coronary heart. If it had swollen any extra, I’d have died.”
