Imtiaz Ali’s latest work of fractured passion Love Aaj Kal features the very massy and commercial Kartik Aryan and Sara Ali Khan doing a realistic love story where every emotion, feeling and dialogue is taken from real life.

“It was just not enough to do the usual romance and courtship. Nor was it enough for Kartik and Sara to draw from their own experiences. Their experiences in the matter of the heart are very limited. In fact, it is limited to one relationship. The one they shared with one another. Neither Sara nor Kartik has been in any serious relationship except the one with each other. Nor have they done any film that can even remotely be considered neo-realistic like Love Aaj Kal,” says a source close to the project.

While Kartik has so far done rom-com like Pyaar Ka Punchnaama and Lukka Chuppi, Sara did the larger-than-life love-across-the-border drama Kedarnath. Both the actors have gone far beyond their comfort level in Love Aaj Kal.

Bizarrely, Kartik and Sara were in a relationship during the making of Love Aaj Kal. They broke up as the film was completed.

Way back in 2007, Shahid Kapoor and Kareena Kapoor’s relationship ended when Imtiaz Ali’s Jab We Met was completed. Kareena and Shahid shot the end-titles song Nagara after they had broken up.

Apparently Kartik and Sara have also shot their final song for Love Aaj Kal after their breakup.
