Filmmaker Shoojit Sircar has collaborated with late actor Irrfan Khan's son Babil for a project, the makers announced on Saturday.

Khan, who passed away last year in April, shared an equation beyond that of an actor-director with Sircar. The duo worked together on 2015 comedy-drama 'Piku', also featuring megastar Amitabh Bachchan and Deepika Padukone.
