Yes, Sylvester Stallone is the only actor to appear on the list twice. That tells you how nuts he is. This story happened during the making of Rocky IV - arguably the best Rocky film. It's the first time you actually feel as though Rocky can't win against the brutal Drago. That's because the real-life actor, Dolph Lundgren outmatches Stallone in every department, including strength. After several movie-style matches where none of the punches thrown were real, Stallone decided it just looked terrible on camera and he and Lundgren agreed they would engage in legitimate sparring, which in their minds was the only way to get a realistic looking fight. Lots of real punches were thrown and, you have to admit, they do look pretty damn bad-ass, just like a real life boxing match. However, for the climactic punch Stallone told Lundgren to hit him as hard as possible. Lundgren, having no bearing on reality, threw a punch that caused Stallone's heart to swell and sent him straight to intensive care for 8 days in Santa Monica. Stallone later said that he believed Dolph could fight in the real heavyweight leagues and that he was stupid to take a real punch from him. Gee, ya think?
