The 72-year-old actor started his career as a executive in a company in the city and has shot many films in Kolkata throughout his career.
"I see some cut and edited scenes from 'Piku' with Shoojit as we discuss the next schedule in Kolkata, Delhi and Gujarat, a longish outdoor. Kolkata shall bring back old memories of my seven year stint as an executive in a Company.. it shall bring back the films shot there "The love and the passion of Bengal is overwhelming.
Whenever in doubt or discomfort of your disposition, visit Kolkata... the people shall pick you up as their own and fill you with their cheer and affection... always," Bachchan posted on his blog.
'Piku' also stars Irrfan Khan, Deepika Padukone, Moushumi Chatterjee and Jishu Sengupta. It explores the father and daughter relationship between Bachchan and Padukone's characters.
Besides Kolkata, the film will also be shot in Delhi and parts of Gujarat.
"Delhi has been home for many years.. its detailing has often been repeated.. but no matter how extensively we may express our feelings for a city that has been your abode for long, it is never enough to completely describe it.
"Gujarat is the new home. Those visits for the tourism campaign has given me the love of the lovable affable and most hospitable people of the region," Bachchan said.
