Indian movies are the most-seen movies in the world, beyond even the billion-strong audience in India itself.

This series talks to Bollywood directors, stars, writers and critics.
It shows a different, far more serious Bollywood than is usually presented - unravelling a century long, and often deliciously mischievous tradition of Indian politics and counter-culture.
Bollywood is the largest film industry in the world, producing over 800 movies a year and captivating audiences of well over a billion throughout India and around the world.
It's famous for its spectacle - sweeping melodrama and terrific song and dance numbers.
But look beneath the surface and there's a Bollywood that's less well known - a canny social engineer, political agitator and moral focus for a newly independent nation.
