Sylvester Stallone has revealed he took some big hits from Dolph Lundgren while making "Rocky IV," and had to be rushed to a hospital because of it.
"He pulverized me," Stallone said in a documentary on the actor's YouTube channel about the making of the movie. "I didn't feel it at the moment, but later that night my heart started to swell."
Stallone compared the injury to when your chest hits the car's steering wheel when you're in a car accident.
"My blood pressure went up to 260 and they thought I was going to be talking to angels," he said.
The actor said he was put on a "low altitude flight" from Canada to the intensive care unit at St. John's Hospital in Santa Monica, California, where he stayed for four days.
"I'm in intensive care surrounded by nuns," he said. "And then after that, I had to go back and finish the fight."
Stallone said that the punch to the chest delivered by Lundgren, who played the giant Soviet boxer Ivan Drago, is in the movie.
"How could you take that out?" Stallone said.
"Rocky IV" is part of the beloved "Rocky" franchise, in which Stallone plays scrappy boxer, Rocky Balboa. By the fourth movie, he's established himself as a world boxing champion and after the death of his friend Apollo Creed (Carl Weathers) at the hands of Drago, he travels to the Soviet Union to fight him.
A director's cut of "Rocky IV" will be in select theaters for one day only on November 11.
