BY the law of averages, eight out of 10 home computers on Yari Road in Mumbai sit on folding tables. Hack into their hard drive with your mind’s eye and the possibilities are immense: The script of the next Bollywood blockbuster, the flawless curriculum vitae of an emerging actor, the photo library of a ramp animal, an address book that shames the 608-page blue-lettered Rubeena Film Directory. Or a twist in the storyline of a mega afternoon soap that will ruin the lunch of half a nation. Learning acting is hard work, when the teacher is Kishore Namit Kapoor, who has also taught Hrithik RoshanSanjay Chauhan lives off Yari Road. Four flights of stairs and his one-bedroom flat is cool and dark. The television is on mute and flickering images illuminate the room. The computer (on the folding table) is ancient. Chauhan is a scriptwriter, his wife Sarita is a painter. They have a school-going daughter called Sara. Chauhan moved here from Delhi a couple of years ago. You wonder what it takes to uproot a man from a stable job, his wife from a spacious studio, and his daughter from her supportive grandparents. He wanted to write scripts full time. In his worldview, Delhi stands for journalism — realism, in a sense — and Mumbai, for fiction. Sipping tea from a brand new Picasso mug, he is emphatic: ‘‘Film fascinates every Indian.’’
