Actor Randeep Hooda will play the titular role in "Sarabjit", a biopic on the slain Indian prisoner Sarabjit Singh and his sister's struggle for his release.
Co-starring Aishwarya Rai Bachchan as Sarabjit's elder sister Dalbir Kaur, the film will be directed by "Mary Kom" helmer Omung Kumar.
Sarabjit, an Indian national, was convicted of terrorism and spying by a Pakistani court and sentenced to death in 1991 but the government had stayed his execution for an indefinite period in 2008.
Dalbir fought for her brother's release from the Lahore jail but her quest ended tragically when he died in 2013 following a brutal attack by fellow prisoners.
Aishwarya, 41, and Randeep, 38, will be seen sharing screen space for the first time.
"Yes Aishwarya Rai Bachchan and Randeep Hooda are going to be a part of my next biopic Sarbjit," Omung said in a statement.
Produced by Sandeep Singh, Zeeshan Quadri and Omung, "Sarabjit" will begin filming in October release in May 2016.
