Answer by Mayank Parakh:
Bob Biswas, the insurance agent-cum-assassin, played by Saswata Chatterjee in the movie Kahaani.
He's not the usual Bollywood villain. There's no psychopathic laughter. No stab of excitement. Not much dialogues even. With just his trademark monologue, "Nomoshkar…ek minute,” which he utters before pulling out his gun in a most nonchalant way and brutally finishing his victim, he manages to terrify both his victims and the audience, alike.
For me he was the highlight of the film, stealing limelight from likes of Vidya Balan and Niwazuddin Siddique.
