Aamir came up with the idea of a promotional video because all the three stars don't appear together in any frame during the movie.
The music video is also supposed to be the only sequence where all the three actors come together.
"Yes its true Aamir came up with the idea of shooting a music video with all three stars together and we all instantly agreed. It is a great idea as having Aamir Khan, Rani Mukherjee and Kareena Kapoor dancing together in a music video is the recipe for total entertainment," said a spokesperson from Excel Entertainment.
The psychological thrilleris written and directed by Kagti and the project is jointly produced by Excel and Aamir Khan Productions.
"Talaash" is also one of the most awaited films of the year because it's Aamir's first release post the superhit "3 Idiots" in 2009.
