In Vidya Balan’s simplicity, lies her sensuousness, avers Rajkumar Santoshi who has Vidya essaying the difficult role of the woman behind Ajay Devgan’s success in Halla Bol .

Her transformation from the small-town girl who loves a struggling actor to the woman who is a successful star wife, and her strife and how she confronts him with moral ethics is a remarkable graph of Vidya’s character and she has played the role with aplomb.”
