Actress Swara Bhaskar, who impressed viewers with her powerful performance as Amaya in “Listen Amaya,” will play Salman Khan’s sister, a pivotal character, in the much anticipated Diwali release, “Prem Ratan Dhan Payo” which has Sonam Kapoor opposite Khan. “My character is strong-willed with a unique personality. She shares an interesting relationship with Salman and her journey is central to the film’s plot. Prem… is the story of siblings and their relationships,” says Bhaskar, adding that while the film is a family drama on the lines of “Hum Saath Saath Hai,” it does not feature a joint family.
