Filmmaker Anurag Kashyap is thrilled with the story line of Kahaani and says that the film's leading lady of the movie Vidya Balan is a true successor of superstar Aamir Khan when it comes to choice of scripts.

"Kahaani is how a thriller should be shot...the ending is debatable but what an effort," the 39-year-old tweeted. "Vidya is slowly emerging to be a true successor of Aamir(Khan)... a great career is defined by choices one makes and courage to see it through," Kashyap added.

Produced and directed by Sujoy Ghosh, this Vidya's another woman-centric film after Ishqiya, No One Killed Jessica and The Dirty Picture. The film also features Bengali actor Parambrata Chattopadhyay and Nawazuddin Siddiqui in prominent roles.
