The makers of Karzzzz have decided to retain the signature tune of the film, which plays in the background the moment the protagonist remembers his punar janam. "It's a haunting tune and all of us decided that we should use it in the remake as well," Satish Kaushik tells me.
While Himesh has already recorded fresh songs for the remake, there's one song that they've decided to retain from the original -- 'Ik Haseena Thi, Ik Deewana Tha' -- which comes at the climax of the film.
While on Karzzzz, Himesh is participating in acting workshops to get the character right. After all, not just the film or its music, even Himesh's performance will be viewed with a magnifying glass and compared to the power-packed performance that Rishi Kapoor pitched in, in the original.
