The New India is yet another interesting documentary from BBC. Might be a few years old (2013), but still - for a person who never has been to India, very interesting :)
In the film, it is told about how India is rising, and how it after one generation could reach 3d largest economy in the world. Top 10 Largest Economies In The World by GDP Nominal (2015)
Meanwhile many live in Poverty. About Nazi ideas in India's nationalist minds. About cast system. And the clash of Muslim and Hindu people.
