The two are in fact an intrinsic part of Kahaani. Mr Bachchan has sung the Rabindra Sangeet in the Vidya Balan starrer.
And now Sujoy intends to move to Bengali literature. He will be filming an adaptation of Bangla litterateur Sunil Gangopadhyay's novel Aranyer Din Ratri with Vidya Balan and the Big B playing stellar roles.
The novel had been filmed by Satyajit Ray in 1970.
Says Sujoy, "At the moment I'm just enjoying the recognition that has come to me. I've waited so long for it. I'm in Kolkata and I see the expectations in people's eyes.
I've to go beyond Kahaani now. I've to live with the novel Aranyer Din Ratri for at least six months. I have to see where I can take it. After all. It's been done by Ray before. And Gautam Ghose also made a sequel Abar Aranye in 2003 to the Ray film. So I'll have to route the novel in a completely different direction. "
That the Big B and Vidya Balan would be part of the literary adaptation is for sure.
"I can't see myself making any films without them. Aranyer Din Ratri is a deep novel. I want to take my cinema beyond Kahaani now. "
