Four Little Calcutta Kids Take On Polio And Apathy And Win

When filmmakers Nicole Newnham and Maren Grainger-Monsen first called former lawyer Amlan Ganguly of the Indian NGO Prayasam to approach him about being involved in a documentary project they were making about facilitators of social change, he quickly hung up on them.

“He told us to call him back at what would be 2 a.m. his time because he was so busy with the children,” Newnham recalls of the first conversation with the Prayasam founder. The NGO empowers kids to change their own social conditions within their Calcutta slum community.

“We had an incredible talk with him in the middle of the night his time,” recalls Newnham, “and we were just really struck by his passion and his dedication and his creativity.”
