Filmmaker Sujoy Ghosh, who is planning a sequel to "Kahaani", is first set to work on a project that he says will "definitely" have Amitabh Bachchan and Vidya Balan in it.
Both actors form an intrinsic part of "Kahaani". While Big B sang "Ekla chalo re", Vidya played the lead in the movie, and has earned appreciation galore for her portrayal of a woman in search of her missing husband.
After "Kahaani", Ghosh intends to move to Bengali literature. He will be filming an adaptation of Bengali novelist Sunil Gangopadhyay's "Aranyer Din Ratri" with Vidya and Amitabh playing stellar roles.
"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," said Ghosh.
The novel had been first filmed by Satyajit Ray in 1970.
Ghosh is content with the response to "Kahaani", and wants to take it forward with the new film. He hopes to give it a different feel than the maverick Ray.
"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," said Ghosh, who earlier worked with Amitabh in "Aladin".
