But trust him to not make a song and dance about it.
"It's nothing," he brushes off what any other actor would have taken as a cue for a shooting break. "I was shooting a dance. While doing a movement something gave way in my hand. But it's in control. No big deal".
But director Sujoy Ghosh has another story to tell. "Sir is in considerable pain. But he insists on continuing. Any one else would have curled up and called off the shoot. But that's what makes him special.
When the injury happened on Thursday he didn't allow us to know what happened. Throughout the day he hid his pain and continued dancing. Only at the end of the day did we get to know what had happened."
But for the Big B the show has to go on. "Yes, it's true I've continued shooting. Can't allow losses on the job, as far as possible. It's okay. Such things happen in life. A ligament in my wrist is torn. The treatment is on. I should be all right in a week."
As him if he's in pain, and the Big B manfully admits he is.
Who says mard ko dard nahin hota?!
Incidentally the Big B was seriously injured on the sets of Coolie and hospitalized for two months in 1983. He has forbidden his son Abhishek from performing dangerous stunts and dance movements.
Apparently the rule doesn't apply to the Big B himself.
