Amitabh is in Bhopal to shoot Prakash Jha's Satyagraha.
"The co-operation of the people of Bhopal is extraordinary. Their discipline, their sense of order, their pleasant demeanours and all that a film unit would expect from an audience when shooting outdoors, is present there in abundance," the 70-year-old posted on his blog srbachchan.tumblr.com.
"My salutations to the city and to the people! Thank you for your effort in allowing us to conduct our work in an atmosphere of required peace and comfort," said Big B, whose wife Jaya's family stays in Bhopal.
