Akshay Kumar was very unhappy with the film and refused to promote it, even though it was made by his own production company.
The song "Kafirana" originally included the lyrics "I wanna fakht you." Indian censors objected, saying it sounded too much like the English profanity, so the lyric was changed to "I want just you."
The film was first planned as " Alien Sahib" with John Abraham in the lead role. John was to also co produce the film. Later John left the film and Akshay was approached.
Akshay Kumar second film with Sonakshi Sinha after Rowdy Rathore and Shreyas Taldpade after Housefull 2 in the same year 2012.
Akshay Kumar had fallout with Shirish Kunder and hence didn't show interest in the film during its release.
