Kolkata: Superstar Amitabh Bachchan suddenly fell ill while shooting for his upcoming movie 'Piku' here on Monday.
Big B suddenly fell unconscious in between a shoot of the movie, for which he had to ride a bicycle.
As per the doctors, he has been diagnosed with Vasovagal Syncope syndrome. It is being learnt that staying hungry for long hours, minimum consumption of water and working strenuously are the reasons for the occurrence of this syndrome.
The 72-year-old actor had landed in the capital city of West Bengal yesterday, from where he had started his new celluloid journey, riding a bicycle past the iconic Writers' Building here.
Wearing a loose cap, which covered part of his bearded face and with a pot belly, Bachchan was shooting for the Shoojit Sircar film which explores father-daughter relationship.
The veteran actor had spent the entire day cycling around the streets of Kolkata, in severe heat, after which he fell ill. He was shooting along with co-stars Deepika Padukone and Irrfan Khan.
However, Big B posed before the camera again after taking rest for an hour, as per sources.
As he cycled, dressed in a pink kurta with a blue sweater over it and sporting a hearing aid, lensmen stood on the roadside taking his photos.
Sircar, who has to his credits films like 'Vicky Donor' and 'Madras Cafe', was present throughout the shooting , which soon attracted a number of spectators.
Bachchan has a long-standing relation with the city as it was from here that he went to Bollywood.
