The sister of Sarabjit Singh, Dalbir Kaur spent more than 20 years of her life for her brother's independence from Pakistan prison. This fight caught the attention of director Hansal Mehta and was inspired to make a film on Sarabjit Singh's life. Hansal Mehta has always directed heartfelt films like Citylights and biopics like Shahid and this year's upcoming film Aligarh, so this movie seems like a perfect fit.
The story of Sarabjit Singh's death created a national ruckus and Dalbir's struggle to free her brother captured the nation's imagination. This certainly caught Hansal's attention and started working on the script of this film. The filmmaker's spokesperson confirmed by saying, "Yes, Hansal has met and spoken to Kangana. An official announcement will be made when things are finalised."
