The much-anticipated trailer for Nag Ashwin's Kalki 2898 AD has finally been unveiled, setting the stage for what is being billed as the "greatest battle" of the year. Featuring an impressive cast led by Prabhas and Amitabh Bachchan, the film teases a grand dystopian saga with stunning visuals and a complex narrative. The trailer opens with the depiction of Kaashi, the last surviving city in a bleak, dystopian future. The city is depicted as a haven for desperate refugees seeking basic necessities like water, food, and shelter. Governed by a ruthless king (portrayed by Saswata Chatterjee), Kaashi becomes the epicentre of a profound conflict. Deepika Padukone's character, a pregnant woman, becomes central to the plot as Amitabh’s character, Ashwatthama, reveals that she is carrying a divine being in her womb. The king, aware of this prophecy, aims to capture her, believing the child to be his nemesis. Enter Prabhas as Bhairava, a warrior with a formidable reputation who asserts he never loses a battle. Adding to the intrigue, Kamal Haasan appears in a surprising, almost unrecognisable role, while Disha Patani also plays a significant part in the unfolding drama.
