Yes, now we will be subjected to the adventures of Genu Gayen and Bapi Bayen. It is a good thing that Satyajit Ray was cremated.
A friend of mine said that once Rabindranath died, we started to live off of every hair from his beard that he shed. Every year at the Kolkata Book Fair there are hundreds of scholarly books still published on Rabindranath Tagore. When Satyajit Ray died, there was a mad scramble of every scrap of paper he ever wrote on, every unfinished story and every outline.
And now we have other writers making spin-offs of their immortal creations!
