Author Tejaswini Apte Rahm talks to me about the history of cinema in India and walks me through her early childhood memories in Bombay (now Mumbai).

We realise our earliest movie memories were identifications with an elephant and an alien, both of which left us traumatised.

I learn about the difference between Bollywood and Hindi films, and how pot boilers and masala movies give you your money's worth.

We also manage to discuss the importance of stories to an understanding of the world and the construction of a moral code, and grapple with Time's Arrow and the Theory of Relativity.

Pretty good for 90 minutes...
