 Ghosh, who co-wrote the story and the screenplay, began to plan the film while awaiting the release of his previous film Aladin (2009), but the dismal response to Aladin was a setback. He had to approach several producers to finance him for Kahaani, but was refused and discouraged from making the film owing to three factors: a pregnant woman as the lead star, a bunch of unknown Bengali actors as the supporting cast and Kolkata as a backdrop. Yashraj Films were willing to produce the film, but wanted Ghosh to sign a three-film deal, which he declined because he did not want that much commitment.
