"It was Amitji who asked me if I was happy... content with the casting (Smita, Parveen and Amitabh) and do I feel it is the ideal casting. I told him I wanted to cast him, Jayaji and Rekha. He took a long pause and told me that he was fine with the decision but asked me to convince the two actresses. I was always on tenterhooks and scared because it was real life coming into reel life. I had told both (Jaya and Rekha) of them that koi gadbadi na ho."

After your marriage, have you had an affair with any other woman?’ If he was stunned, leave aside upset, Amitabh did not show it. My eyes were on him as I spoke and he was looking back at me equally intently. But his face was unperturbed. I don’t even recall his expression changing.
