Katrina Kaif`s song `Husn Parcham` from Zero had created a rage when the song was unveiled.

`Husn Parcham` starring Katrina as the glamorous icon became a blockbuster since its release.

The makers of `Zero` have now released a video which shows what went behind the making of this song.

While the song has been choreographed by Bosco, the director of `Zero`, Aanand L Rai, also gave his inputs.

However, one very important input which took the song a notch higher was from Bosco himself, who suggested that Katrina make the gesture of `call me`.

Even though the team found it ok at first, they still went ahead with the scene and the results of it are all quite visible.
