Sujoy Ghosh is all set to bring a sequel of his 2012 hit film 'Kahaani'. The director says he started 'Kahaani 2: Durga Rani Singh' as a new and different story.

"We have Durga Rani Singh this time. When we set out to make this film, we made a very conscious decision not to have anything attached to 'Kahaani'. We made a separate story; it has to be completely independent. We are going to be compared so rather not attach any spill over from 'Kahaani'," Ghosh said at the trailer launch of the film, which stars Vidya Balan in the lead.

He added that there would be more interesting characters in the film.

Talking about the name - Durga Rani Singh - Ghosh said: "We really liked that name so we kept that. I think a sequel should have an identity of its own whether it's Vidya Bagchi or Durga Rani Singh. Instead of calling it just 'Kahaani 2' we must have an identification."

'Kahaani 2: Durga Rani Singh' also stars Arjun Rampal and is slated to release on December 2.
