"Our animation 'Mahabharat' is meant for today's grandfathers to show it to their grandchildren. I want to show it to Amitabhji and his grandchildren too," Gada said in a statement.
Amitabh has three grandchildren - Agastya, Navya Naveli and Aaradhya.
Sunny Deol, Ajay Devgn, Anil Kapoor, Manoj Bajpayee and Vidya Balan have also given voice overs for the film.
