After the super success of his film 'Kahaani', filmmaker Sujoy Ghosh is already preparing for his next. 

Though the film is currently in its writing stage, he recently confessed that if things fall in place, he is dreaming to manage a casting coup. 

After getting to work with national award winner Vidya Balan in his aforementioned film, he plans to direct Amitabh Bachchan with whom he has earlier worked in 'Aladin' as well as recorded a song for 'Kahaani. 

But apart from Amitabh and Vidya, he also plans to cast veteran Naseeruddin Shah in the film. 

He revealed his ambitious plan on his microblogging page recently - "The script that I'm writing for sir (Amitabh Bachchan) is called BADLA, which, if I write well, will have sir and Naseer ji and Vidya balan. all depends on script," wrote Sujoy.

He also cleared that the film isn't a sequel to his last hit, "and finally…BADLA is not the sequel to Kahaani. thats another story altogether," posted Sujoy later. 

Well, if this turns out to be true, it will be a double whammy for Vidya who has worked with Amitabh and Naseer in 'Paa' and 'Ishqiya' respectively.
