The film was planned in 2005 but was shelved for some reason and Farah Khan went on to make Om Shanti Om (2007), and Tees Maar Khan (2010).
In the end we get a glimpse of SRK's youngest son AbRam.
Shahrukh in a scene says "Picture abhi baaki hai mere dost", which is his famous dialogue from "Om Shanti Om".
This is the second time, after "Chennai Express" that Shah Rukh Khan has put his heroine's name ahead of the rest of the cast in the opening credits.
The movie already had earned more than Rs 400 Crores before release. Rs 200 Cr from selling television and music rights and Rs 200 Cr from its promotion.
