That's right. When Prabhas was told about Baahubali he was told about Amarendra Baahubali and his romance with Devasena. But little did he know about Devasena turning mother to Shivudu played by him.
So the actor revealed that he could not get the chemistry of a son and mother right with Anushka. There is a reason for this; Prabhas and Anushka's pair is a hit jodi and there were rumours too about some love bloomed between them although both of the actors rubbished it.
It was under these circumstances Prabhas struggled to strike chemistry that'd be there between a son and a mother. This will be seen in the second part soon!
