JOIN USSylvester Stallone says years of doing action films has injured his body as well as Arnold Schwarzenegger's, and adds that there is a limit to enduring physical pain.
"It comes at a price. Arnie must have lifted a million pounds of weights in his life but it comes at a price. There's only so far you can push the machine, then it's a case of taking it to the mechanic to get this part fixed or that part fixed. These days that happens more and more," Stallone said.
However, the 66-year-old actor loves taking up the challenge raw action throws at him, reports contactmusic.com
"I don't know how people do that green-screen work. I've done a bit and it drives me crazy. I like the heat of an explosion in my face, a hunk of tin flying past my head 30ft from where it should have gone. It's hard to get the emotion without it. I'm very proud of this movie because 90 percent of the stunts are in camera," he said.
"I still love the challenge. I get there and I go, 'Let me jump off, let me go into the water'," he added.
Stallone and Schwarzenegger will soon be seen in their forthcoming movie "The Expendables 2" coming out Aug 17.
