Dalbir Kaur, 61, is the older sister of Sarbjit Singh, a farmer from Bhikhiwind in Punjab (just 5 kms away from the Indo-Pakistan border), who in 1990 while farming, inadvertently, crossed over to Pakistan after having a couple of drinks, got mistaken as an Indian spy and was given capital punishment in 1991 but was not hanged. He was kept in the Kot Lakhpat jail in Lahore for 23 years, before he was killed by inmates a few days after the death of Afzal Guru in India. During his 23 years in jail, his sister Dalbir Kaur, who treated him more like her son than her brother, got to meet him only thrice in jail and made it her life's agenda to get him released. While she finally did not succeed in getting him released, she is determined to reach his real story to the world through a film titled Sarbjit being made based on his life that is being directed by Omung Kumar (has earlier directed Mary Kom). The story of Dalbir's battle and finally defeat for not being able to bring her brother back alive is not just touching but heartbreaking. We have exclusively learnt that Aishwarya Rai Bachchan has given her nod for playing the part of Dalbir. Aishwarya is not just one of the world's most beautiful women, but she is a great actress and thus, she is a great choice for this role. Will now wait to see who plays Sarbjit.
