Bachchan, 81, who essayed the role of immortal warrior Ashwathhama in the film, earlier expressed his admiration for the project in a lengthy post on his personal blog.

Calling it a “massive spectacle”, the actor said the film is a “merger of myth and reality” and a “learning to the film makers on the process of putting the mammoth together for a viewing audience.”

Kalki 2898 AD is reportedly the most expensive film ever made in India with a budget of Rs 600 crore. The film had a global release on June 27 in five different languages, Telugu, Tamil, Malayalam, Kannada, Hindi and English.

Previously titled as Project K, the film has been described as a fusion of Hindu epic Mahabharata and science fiction. It also stars Saswata Chatterjee and Shobhana in pivotal roles.

The film is currently running in theatres.
