Filmmaker Sujoy Ghosh, who is the creative producer of thriller "TE3N" starring Amitabh Bachchan, Nawazuddin Siddiqui and Vidya Balan, has promised to "work as hard as possible" and even give a bit more to make a good film.

Nawazuddin and Vidya are currently shooting in the historic Writers' Building (the permanent seat of the West Bengal government) here for the Ribhu Dasgupta-helmed venture. They will be joined by Big B later this week.

"Thank you for all your wishes. In return... we will work as hard as possible... and a little bit more... to make a good film for you," Ghosh tweeted on Tuesday.

Around the same time last year, Big B had shot in north Kolkata for "Piku" while in 2010 Ghosh had captured Durga Puja, east India's biggest festival, in the Balan-starrer "Kahaani".
