Las Vegas is an expensive place to shoot, especially during Christmas it turns too tough and costly. However, the film shows the lead characters impulsively getting married on Christmas night in real locations. So debutant director Shakun Batra and producer Karan Johar were keen that the location was neither changed nor cheated upon.
Hence Karan Johar agreed to pay the premium charges to get the requisite permissions to shoot. The film will be starring Kareena Kapoor and Imran Khan.
