With just three films, Karthik Subbaraj has craved a niche place for himself. Some term him as the modern day Mani Ratnam for his subtle but intense scripts. However, there is one actor with whom the Pizza director wants to really work with. It's Bollywood star Nawazuddin Siddique, who is known for his classic performance. The director recently asked the actor openly on Twitter whether he would be willing to work in Tamil films. "@Nawazuddin_S am a filmmaker from Tamilnadu and a big fan of u... Do u have idea of acting in a Tamil film anytime? aª#‎AskNawazuddina¬," Karthik posted.
