Salman Khan’s campaign to free Sarabjit Singh was never part of the script of ‘Sarbjit’, says the film’s director Omung Kumar. According to reports, a part of the story in ‘Sarbjit’ supposedly concerned Salman Khan. In 2012, Salman had campaigned on Twitter to free the real-life Sarabjit Singh from jail in Pakistan where he was confined for over 20 years for alleged spying. The film is about Sarabjit’s sister’s struggle to get him freed.
