John Abraham was originally set to play the role of Arjun Rampal, but he could not do so since the dates of Ravi Chopra's 'Babul' had gone haywire due to Bachchan's health problem. So the role was later performed by Arjun Rampal.

Not many people know that Vikram Chatwal who plays the role of Bunty opposite actress Sandhya Mridul and calls himself "her better half" in the film's trailer is in real-life, an affluent and down-to-earth wealthy Manhattan socialite, having led life in the fast lane. He is a hotelier with Indian roots (and reportedly very close to the Clinton family), and is even rumored to have been "good friends" with supermodels like Gisele Bundchen and Kate Moss.
