Rai and Krishika Lulla.The film features Diana Penty, Abhay Deol, Jimmy Shergill, Ali Fazal and Momal Sheikh in the lead roles. The film marks Rai’s third collaboration with Eros International after Raanjhanaa (2013) and Tanu Weds Manu Returns (2015).
While shooting for the film Raanjhanaa (2013), Abhay Deol was offered the lead role in the film, since it was not a “full-fledged role” in the former. In January 2015, reports suggested that Diana Penty will be starring opposite Deol in the film.In July 2015, it was reported that Ali Fazal will play an important role in the film.In September 2015, it was revealed that Pakistani actress Momal Sheikh will be playing the second lead in the film.
According to Penty, her career in modelling happened by chance, when she sent her modelling photos to Elite Models India, who liked her work and suggested she take on assignments. At this stage, she was in college, and was reluctant to take on a career in modelling, so Penty decided to work part-time as a fashion model.
Filming began on 17 September 2015 in Amritsar.
