But the thinking-man persona was abundant.
Fans circled the building for most part of the day to get a glimpse of Big B.
Amitabh arrived in the city Sunday morning to shoot for "Vicky Donor" director Shoojit Sircar's upcoming film "Piku", where he plays the role of father to Deepika Padukone.
The Bollywood superstar Sunday became nostalgic and relished "too many memories" of Kolkata as he pedalled on a bicycle, with a twinkle in his eyes, through the city's nerve centre BBD Bagh that houses numerous heritage structures as also the Writers Buildings - the regular seat of the West Bengal government. Amitabh had migrated to the eastern metropolis in search of a future and a job in the early 1960s and survived on a salary of Rs.500 by working for a private company. Later, he switched to Mumbai to make it big on the silver screen. He cycled Sunday afternoon as part of the shooting for the film that is scheduled to hit the screens April 30, 2015.
