Enter Naseeruddin Shah, who has the unenviable job of counselling them through the inevitable romantic distress. OK Jaanu ventures into mostly uncharted territory - only a handful of previous films, including Kangana Ranaut's Katti Batti, have explored live-in relationships - and at several points, director Shaad Ali appears to have been unable to escape Bollywood's habit of pontificating on morality: "Yeh jo hum kar rahe hain, yeh theek hain?" asks Tara of Adi after an intimate moment. But the trailer of OK Jaanu is made charming by its lead actors, who have previous experience of filmy aashiqui, having delivered one of 2013's big romantic hits together.

The trailer of OK Jaanu was heralded by the poster, tweeted last week:
OK Jaanu's other credits are impressive - A R Rahman provides the soundtrack, Gulzar the dialogues and lyrics. Mani Ratnam, who directed the original movie, and Karan Johar produce.
OK Jaanu is the first of next year's films, opening on January 13, 2017.
