Arjun Kapoor says he signed "Sardar Ka Grandson" for his grandparents. He adds that a story can be told if one relates to it -- not necessarily the character but the overall emotions of the story. "Sardar Ka Grandson" revolves around a grandmother`s last wish, and also features Neena Gupta, Rakulpreet Singh, Kanlwajit Singh, John Abraham, Aditi Rao Hydari and Kumud Mishra.

"My nani (maternal grandmother) was a ferocious woman -- both my grandmothers. Till the day she (nani) died she was in the hospital suffering from cancer and she was still talking to me. She handled my finances till the day she passed away because I lost my mother before that. So, I was close to my nani. She was a producer herself," Arjun told IANS.
