The 72-year-old actor is portraying the role of an aged father in 'Piku'. The film explores relationship between Bachchan's character and Deepika Padukone, who plays his daughter.
"In 'Piku' land...!! Too many memories flashing by as the drive from the airport ends but so much more to come in the days ahead... Kolkata shall always hold a special place and space within.. A 'city of joy' that energises you with intellect and passion," Bachchan posted on Twitter.
The film also stars Irrfan Khan.
