The 73-year-old "Wazir" star was shooting in and around Kolkata and for him no pain in "greater" than that of going away from love of people of the city.
"The filming is over of 'TE3N' and I am back to familiar addresses.
"The withdrawal symptoms predominated at the closing of the 'last shot' with the unit, as is won't and the disappearance from the love of the Kolkatans is truly the pain greater than any other. How can one ever repay this?," Bachchan wrote in his blog.
He also posted a picture of fans mobbing his car to see a glimpse of him during his departure from the city.
