The film is based on a women-centric theme and has Rani Mukherjee, Konkona Sen Sharma and Jaya Bachchan (all Bengalis) in central roles. Not just the leading ladies, even the film's director Pradeep Sarkar is a Bengali.
With such a strong bong connection in the film's crew, the actresses bonded real well. They chatted in Bengali and often ordered various Bengali cuisines like Rasagulla and Mishi Doi on the sets.
In this bong bonhomie, Punjabi munda Kunal Kapoor felt a bit left out as he was not able to understand the jokes that the ladies were cracking in Bengali. However, he bonded real well with his co-star Konkona Sen. ‘Laaga Chunari Mein Daag' also has a special appearance by Abhishek Bachchan. The film has been shot in Varanasi, Switzerland and Mumbai.
