Why is Prabhas anxious about 'Baahubali'?

For Telugu superstar Prabhas, it was not easy to play the dual role of a father and son in the upcoming multi-lingual two-part epic drama "Baahubali" as he had to undergo a strict diet and training regime. Prabhas, who is sporting two different looks in the SS Rajamouli directed film- a heavy body for the father Baahubali and a lean physique for his son Shivudu, said he is getting nervous thinking about the fate of the movie. The actor, who was last seen in Telugu action-drama "Mirchi", said he learnt sword fighting, kick-boxing, kung-fu and horse riding for "Baahubali".
