Spending time with grandchildren is the best phase: Bachchan

As a doting grandfather, Bachchan tells stories of "Mahabharat" and "Ramayan" to Aaradhya making her aware of that side of the world as well. "We do narrate her certain things. I will narrate her 'Astra' stories also," he said. When Bachchan was offered the role to play the superhero in "Astra Force", he first thought the makers were not serious about it.
