Few Bollywood relationships have generated as much success and controversy as of these two. Raj cast Nargis in his directorial debut- Aag and they went on to work together in 16 films, six under Raj’s own banner. In most of the films, Nargis at least once appeared in a white sari- an RK trademark. The scene from ‘Barsaat’ with Nargis in Raj’s arms remains the RK films’ logo till this day. It was said that Raj was in love with Nargis, but as he was already married he had to let go of her.
