Actor John Abraham, who will next be seen in Force 2, says he shot for the films, despite going through tremendous pain. “This film has a sequence on a rooftop; and my knee was damaged while shooting it. After that, we shot in Hungary where I underwent two knee operations. I still remember when I wanted to sit in a car, Vipulji (Shah, the producer) would lift my leg and put it in the car because I was not able to move it,” he said.
