India is a huge country with lots of different cultures and languages. Indians themselves like to say that after every 100 kilometer there is a new custom of living, eating and speaking. You could hear lot of different languages while traveling around in India. Bengali community is a very large and well known also outside of India. It is a community that has been split by two countries – India and Bangladesh. Their rich culture has been developing around the Bay of Bengal for long time.
One thing that Bengali people are proud of is their rich culture of arts and films – Bangla movie as they call it. So for example if you are about to watch Hindi movies online, I also recommend watching some Bangla movie. It will give you a different perspective of India and illustrates how diversified the culture in this country could be. But keep in mind that Bangla movie industry is not only centered in Kolkata, the capital of West-Bengal, but a huge amount of it is in Dhaka, the capital of Bangladesh. By the way films made in Kolkata are from Tollywood, by the name of the district in the city and films made in Dhaka a from Dallywood.
Historically Bangla movies have been more arty that Bollywood films. They have for example their famous director Satyajit Ray who was highly talented in this. Nowadays it has been changing a lot.
Rani Mukerji is a Bengali film heroine who is also well known Bollywood actress.
