Actor Aamir Khan, whose new film Thugs of Hindostan is getting mixed reactions, says that his role in the Vijay Krishna Acharya directorial is one of the toughest that he did. Aamir, who will co-host a show on BIG FM for a week, spoke at length about his challenging role in the latest release. “It is one of the toughest roles I have taken up. Not only this, but this is a very unreliable character who can do anything at anytime especially for money, and this is entertaining and fun to watch,” he said in a statement.
