Chennai, Oct 15 : Actress Raashi Khanna, who plays one of the three female leads in director P.S. Mithran's upcoming spy thriller 'Sardar', has called the director brilliant and a feminist. Speaking at a press conference prior to the trailer launch event of the film, which features actor Karthi in the lead, Raashi Khanna said: "Mithran is the most amazing director I have ever worked with. He is extremely, extremely intelligent. "I think the future of our films are in good hands if we have filmmakers like Mithran. After the narration, I was blown away by the story, the screenplay, the way he has written his characters. "I can say that he is a sort of a feminist the way he has written characters for all of us. So well-blended! This is a film where you are basically blending a spy thriller with a social cause. It is so difficult but he has done it and he has done such a great job. "I am so happy I got to work with you Mithran and I really look forward to your future films and I hope that I get to work with you real soon. I think you are brilliant." The film, which is to hit screens on October 21, features Karthi in double action -- one as a spy and another as police officer crazy about publicity.
