Actor Ranbir Kapoor, who is known for his dancing skills, was finding it difficult to shake a leg while shooting for Anurag Basu’s Barfi!. Not that he was unable to get the steps right, but for Ranbir it was ‘Murphy’ becoming the hurdle. Says Ranbir, “For me, it was very difficult as well as challenging to do Ballroom Dancing. Since I am playing the character of a deaf and dumb person, it took time to feel the situation as in how Murphy who cannot hear the music will dance. It was like a big task for me to react and then dance accordingly.”
