Apart from the sizzling lead pair – Hrithik Roshan, Katrina Kaif – and brilliantly choreographed dance sequence, the "Bang Bang" title track has another USP to it.

Composers Vishal Dadlani and Shekhar Ravijani revealed in a recent interview that the song was composed in a few minutes.

"The song was composed in five minutes flat. Vishal and I were jamming on the loop and we came up with an interesting format," Ravijani told Mumbai Mirror.

In the video, Roshan is seen aping Michael Jackson – the king of pop, whereas Kaif flaunts some seductive moves.

Shot in a lavish set with glaring flashbulbs, the sequence has been choreographed by Bosco-Caesar. However, Roshan reportedly said that he had tried to incorporate his style of dance as well.

Dadlani, who has crooned "Tu Meri", says they were thrown with the challenge of creating a number, which would do justice to Roshan's dance moves. "The engineer, while extending the loop erred, and we got an updown-up-down tempo which intrigued us. It was a new sound and we played it back to Siddharth who loved it, so did Hrithik. That's how Tu Meri evolved," added the singer-composer.

Praising the "Krrish 3" actor's infectious energy, Ravijani said that the picturisation of "Tu Meri" was exceptional because there was something new and unique to look forward to.

"This is our fifth film with Siddharth Anand, after 'Salaam Namaste', 'Ta Ra Rum Pum', 'Bachna Ae Haseeno' and 'Anjaana Anjaani'. And in every film, he has taken our songs one step up with the picturisations. We love making music for his movies," noted the music composer.

Peppered with power-packed stunts and death-defying action chases, Siddharth Anand's directorial is scheduled to release on 2 October. The action flick will also feature Jaaved Jaffrey and Danny Denzongpa in pivotal roles.
