After unveiling several posters, teasers and much-talked about delays, the makers of ‘Kalki 2898 AD’ finally released the film’s trailer on Monday. Helmed by Nag Ashwin, the post-apocalyptic film seems to be inspired by Hindu scriptures and is in the year 2898 AD. It features Prabhas as Bhairava, an avatar of the Hindu god Vishnu, while Amitabh Bachchan plays immortal Ashwatthama. The film also features Deepika Padukone, Kamal Haasan, and Disha Patani.
