When I'm shooting on location, you get ideas on the spot - new angles. You make not major changes but important modifications, that you can't do on a set. I do that because you have to be economical.

Well the Bombay film wasn't always like how it is now. It did have a local industry. There were realistic films made on local scenes. But it gradually changed over the years.

My films play only in Bengal, and my audience is the educated middle class in the cities and small towns. They also play in Bombay, Madras and Delhi where there is a Bengali population.

Sometimes a director is making three films. Perhaps he is shooting a film in Madras and a film in Bombay and he can't leave Madras as some shooting has to be done, so he directs by telephone. The shooting takes place. On schedule.

Ever since Two Daughters I've been composing my own music.

The director is the only person who knows what the film is about.

Most of the top actors and actresses may be working in ten or twelve films at the same time, so they will give one director two hours and maybe shoot in Bombay in the morning and Madras in the evening. It happens.
