Vicky Kaushal has started preparing for one of his most-awaited and perhaps biggest films, ‘The Immortal Ashwatthama’. The central character of Ashwatthama is taken from the epic mythology Mahabharata, where he is known to be immortal. As per the story, Ashwatthama still lives. The makers though haven’t revealed much story details of their film. ‘The Immortal Ashwatthama’ is directed by Aditya Dhar, who worked with Vicky in ‘Uri: The Surgical Strike’. That film was a super-duper hit and swept most awards that year. Talking about ‘The Immortal Ashwatthama’, Vicky posted on his Insta handle, “When the director’s really serious about ‘casting’ you in the Film. Prepping to be The Immortal!” showing how his life-sized Plaster of Paris (PoP) cast is getting ready, along with a picture. According to unconfirmed reports, Sara Ali Khan has been signed to star opposite Vicky Kaushal.
