Dia Mirza signed for the part of Puja in the movie; however, due to the failure of her previous films, Anupam Kher gave her a condition of working on the film for free, which she did not agree to.

Originally Yash Raj Films wanted to rope in director Anupam Kher with his script and also wished to produce it, in a condition that the director managed to rope in Aamir Khan (Om), Shahrukh Khan (Jai), Salman Khan (Jagadish), Kajol (Ayesha), Rani Mukherji (Neetu)& Preity Zinta (Pooja) playing the leading characters. However, surprisingly, all the actors declined the film stating date problems and the project was eventually produced by Vashu Bhagnani and released by Sa Re Ga Ma HMV.

Some part of the film is shot in Dunedin, New Zealand. The university campus is University of Otago's campus. In the movie, the location referred to as Atlanta, United State is Dunedin, New Zealand.
