Kalki 2898 AD Release Trailer

Plot from Wikipedia:

In 2898 AD, the desertified city of Kasi is now the only city known to exist, ruled by a totalitarian elite, led by god king Supreme Yaskin, from a hovering inverted-pyramidal-megastructure above the city, known as the “Complex”. Set against the backdrop of ancient Indian Hindu mythology and a dystopian society, the story chronicles the journey spanning millennia, from the events of the Mahabharata in the year 3102 BC, the beginning of Kali Yuga, to 2898 AD. The core of the narrative revolves around the arrival of enigmatic figure of Kalki, the tenth and final avatar of the Hindu deity, Vishnu.

It is the most expensive Indian film ever made.
