Choreographer Ganesh Acharya, who directed Katrina Kaif\'s dance moves in the popular item number Chikni Chameli, says she was the perfect choice for the number and that nobody could have done justice to the song. \"Katrina has done a lot of hard work for the song. She has given all the power and dedication that was needed,\" said Acharya. \"We choreographers only choreograph the song, but it is the artist who makes all the difference. She did it very nicely,\" he said. Acharya is known for choreographing item numbers like Beedi in Omkara and Shalu ke thumke in Bin Bulaye Baraati. The song, composed by National Award-winning duo Ajay-Atul and sung by Shreya Ghoshal, has become the USP of Karan Johar\'s Agneepath, a remake of the 1990 Amitabh Bachchan-starrer of the same name. It has garnered over five million views on YouTube. The action-drama, slated for a January 26 release, features Hrithik Roshan as Vijay Dinanath Chauhan, originally played by Amitabh. Priyanka Chopra, Sanjay Dutt and Rishi Kapoor will also be seen in key roles in the movie.
