Bollywood ? There is a place called Mumbai ( BOMBAY ) in India where HINDI films are made. It is also considered the biggest
film industry in the world, because it makes about 700 films a year ( most of which are pure pulp junk )
He knows that, he was just dismissing Bollywood as not worth talking about.
And Bollywood is only a small part of the Indian film industry. Apparently the same amount of films are made outside of Bollywood.
