“Nothing was shot in original Dharavi in Bombay, except for stock shots. For seven days I’d walk around the studio like a madcap, then I took some photographs and put them in my room and watched them. In Dharavi where I spent two days, I made some sketches by these photographs. I tried to decide which temple or what house I should put where. Then, we started erecting the sets; they were done in 20 days.”
