'Uri: The Surgical Strike' director Aditya Dhar, who is collaborating with Vicky Kaushal for 'The Immortal Ashwatthama' said it'll be a trilogy. "For now, we're concentrating on...first part...if we perfect that...[next parts] will be made," he added. On choosing Ashwatthama's character from 'Mahabharata', Dhar said, "He was arrogant, egoistic...that made him more human than...other characters."
