Amitabh Bachchan and director Shoojit Sircar impressed one and all with ‘Piku’. Apparently, Big B too was happy to have worked with such an amazing filmmaker as they have also done a few advertisements together. And now the ace filmmaker and veteran star are all set to unite for the silver screen. Trade reports suggest that Amitabh Bachchan has signed a project with Shoojit Sircar’s production house Rising Sun Films but he will be directed by a new filmmaker. Amitabh Bachchan is currently working on Bejoy Nambiar’s ‘Wazir’ and Sujoy Ghosh’s ‘Te3n’.
