After having brought Kolkata into the limelight with his thriller Kahaani with Vidya Balan and leading Bengali actor Parambrata Chatterjee, Sujoy Ghosh has decided to base his next thriller in Kerala. The director is currently working on the script of the film, titled <em>Kerala</em>. Talking about his film, Sujoy details, "It's a three-hero project of which Parambrata is one. I will have to probably cast two Bollywood actors for an equal number of roles. But I haven’t finalized on the names yet; it's still too early. We shall mostly go on the floors next year."
