Watch: Vidya Balan is stunning and riveting in Kahaani 2 dialogue promo

Mumbai: Vidya Balan has evidently put her acting prowess to full use in Sujoy Ghosh's upcoming directorial and we can't complain.

The trailer of the sequel, 'Kahaani 2: Rani Durga Singh,' revealed that it's going to be even more complex, intriguing and riveting.

The brand new dialogue promo of the film further propels the dark tone of the film, with a raging Vidya going about doing her business. Once again, one can't figure if we are to root for or be wary of her.
