Ghai told IANS: "For Sarabjit's role we have Anurag, the boy who was in 'Black & White'. He is brilliant and one of the finest actors. Our director feels he will play the part well, so we may cast him."
There were reports claiming Sonakshi Sinha will play the role of Sarabjit's sister.
When asked, Ghai said: "Sonakshi is very much on our wish list, but we have not finalised anyone so far. Sarabjit Singh's family has given their approval for the project."
To be directed by Ishwar Singh Muchhal, the biopic will bring to the screen the tragic story of Sarabjit who was convicted for his alleged involvement in the 1990 serial bomb blasts in Lahore and Faisalabad in which 14 people were killed. He was serving his sentence in Lahore's Kot Lakhpat jail and on April 26 his inmates attacked him with bricks and plates and the injuries led to his death.
