Big B was at Rabindranath Tagore's birthplace and ancient community to do a locality film for the version of the National Anthem in his voice. The voice recording was done three days ago at singer-composer Adesh Shrivastava's studio in Mumbai and Bachchan flew down on Saturday to shoot the sequence for the 1-minute-38-second Anthem written by Tagore in 1911.

The legendary actor described Thakurbari as an iconic monument and a historic house that very few people had been to or even knew about. "I doubt if the rest of the country has seen the Thakurbari or even know about it. The house is steeped in history and culture, its rooms full of interesting mementos — from the Nobel Prize to his personal artifacts collected during his journeys abroad. It was interesting to see the paintings Tagore had done later in life. The silence in the room that he breathed his last... it was a great experience, one that has to be experienced. I will spend a lot of time tonight writing about it in my blog," he said.
