> 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 labored. Stallone, suffering from labored 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.
