MUMBAI — From a gangster's girlfriend to schizophrenic to spunky small town girl, actress Kangana Ranaut has portrayed a variety of characters on the screen in the past seven years, but she says her role in "Revolver Rani" is her toughest so far. "My role in Revolver Rani is very difficult to portray. I think ‘Revolver Rani' is my toughest role so far," Kangana said. "It's a very unusual film, in which my looks are very different. I have to look unattractive in the film and for the first time I have to take care that I do not look beautiful," added the actress who apparently took training to use the revolver to make her role believable. — NDTV
