Big B isn't just about playing godfather characters like in RGV's Sarkar, or the ageing father, the actor is also happy playing roles of a grandfather.

He enjoyed playing the title role in Ravi Chopra's Bhoothnath. The actor had fun shooting with a group of kids, but, what caught our attention is that director Vivek Sharma calls Amitabh, dada.

When we quizzed him about it, Vivek simply said, "People consider him to be the baap of cinema, I say he's the baap of baaps. So that makes him dada, na?"
