We have already reported that ace director AR Murugadoss is busy with his Bollywood venture Akira. The film is a remake of Tamil hit Mouna Guru but in the Hindi version the main lead is done by Sonakshi Sinha. In a recent interview, Murugadoss has revealed that he was awed by Sonakshi's dedication and intense performance in the film. "She started training for the role seven to eight months before we went on floors with the film. She had completely detached herself from other projects, enabling to channel all her energy into Akira. She learnt martial arts, cut her hair short, and transformed herself from head to toe," he was quoted saying.
