Watching Kannada movies online is a great idea if you want to get to know the culture of Karnataka before you are about to travel there or you are about to make business in Bangalore for example. But to understand the context I really recommend to watch at least one today’s and one historical Hindi movie before. By doing so you could feel the differences that are represented in different cultures in India. You would also recognize that Hindi movie is always a bit more modern than Kannada ones.
One of the interesting facts that you could investigate is the relationship of a Hindi movie to Soviet Union film industry in last century. You would find that they were closely related, especially if you look at it from Soviet Union side. Actually some of Hindi movie actors become great heroes in Russia those days. Raj Kapoor was adored by huge amount of soviet women for example. When he came to Moscow people recognized him on the streets. Bollywood and Soviet film industry have also made some films together in the past. More closer look gives you a feeling that Bengali film industry was very much connected to Russian cinema. Tarkovski, the great soviet movie maker, was a big example to lot of directors of Bangla movie those days and as I hear also today some student in Satyajit Ray Film Institute set his films on pedestal for themselves.
This is something that you would not find for example in watching Kannada movies online. They represent a bit different India all together.
