Feluda’s world was cleaner, what with Ray also being a film-maker. Maybe he thought in a cinematic perspective first and then the writing emerged, fashioning itself around that vision... on the other hand Saradindu babu was a sharp penman who had no such compunctions about the environment in which his detective resided...His pre-independence Calcutta is sordid, dark and has a seedy underbelly much like Conan Doyle’s London. This is the world that Dibakar Bannerjee successfully recreates...in bold colours and with superb detailing.
Bannerjee, here does something very interesting. He takes three separate stories from the author’s collection and picks the primary characters from them. Then he weaves all of them seamlessly into one plot while keeping the original flavour of the stories intact. This is the best part of the movie, it's screenplay by Dibakar Bannerjee & Urmi Juvekar.
Ajit engages a fresh out of college Byomkesh to locate his father Bhuven babu and the story takes off, taking us along with the protagonists on a joy ride that is truly mysterious...wheels spin within wheels and the knotty situations don’t unravel easily...and this is the beauty of the screenplay, it keeps the viewer totally engaged. Byomkesh finds obstacles, love and adventure in his resolution of the larger plot that emerges out of the simple missing person case.
