Happy Bhag Jayegi (English: Happy Will Run Away) is a 2016 Indian Hindi-language romantic comedy film written and directed by Mudassar Aziz. Produced by Anand L. Rai and Krishika Lulla, it stars Diana Penty as the eponymous heroine, a free-spirited bride-to-be from Amritsar, India, who runs away from her wedding ceremony, but inadvertently ends up in Lahore, Pakistan. The production features an ensemble cast of Penty, Abhay Deol, Jimmy Shergill, Ali Fazal, and Momal Sheikh.
Aziz began writing for the film in 2012 and later approached Rai to produce it. Conceived as a "cross-border" romantic comedy, the film was originally titled Dolly Lahore Mein. Although a large part of the film is set in Lahore, filming was done in various parts of Punjab with Saurabh Goswami working as the director of photography. The film featured Pakistani actors and also marked the Bollywood debut of Sheikh. The music for Happy Bhag Jayegi was composed by Sohail Sen. Eros International acquired the worldwide distribution rights for the production.
Happy Bhag Jayegi was released theatrically in India on 19 August 2016; it opened to mixed response from film critics who appreciated the performances of ensemble and humour in the film. Criticism was focused on the film's scattered screenplay, inconsistent tone and relatively poor characterisation of the central character. Regardless, the film performed well at the box office collecting ₹391 million against a production budget of ₹200 million. It was declared a sleeper hit by media outlets in India.
