Comics are created by people all over the world. I grew up reading many in India, and it looks like someone is making a documentary about India's comic book culture! You can visit their website below, but it'll still be awhile until it is completed, and hopefully subtitled. But anyone interested should definately check it out!
The documentary is called 'Chitrakatha' which means 'Comics' in India's national language, Hindi (Chitra = Pictures, Katha = Story). They also have a Facebook page as well.
