One of the interesting details you could explore is the relationship of a Hindi movie to Soviet Union flick industry in last century. You would discover that they were carefully connected, incredibly if you look at it from Soviet Union side bollywood films . Actually a few of Hindi movie stars become great heroes in Russia those days. Raj Kapoor was admired by huge amount of soviet females for example. When he reached Moscow people recognized him found on the streets. Bollywood plus Soviet flick industry have equally created some movies together in the past. More closer look provides you a feeling which Bengali flick industry was a lot connected to Russian cinema. Tarkovski, the great soviet movie maker, was a big example to great deal of directors of Bangla movie those days so that as I listen equally today some student in Satyajit Ray Film Institute set his movies on pedestal for themselves.
This is anything which youd not discover for example in viewing Kannada films online. They represent a bit different India completely.
