Debutant Sriram Challa is quite confident of his film ‘Control-C’ which is hitting the box office tomorrow. The director had a small chit-chat with media on Thursday and shared his working experience. “For over two decades I’ve worked as software engineer. But my passion towards films drove me here. I’m director Sukumar’s Ekalavya disciple and he encouraged me when I approached him with the script of ‘Control C.’ The film is about a couple who escape from the twin tower attack in US and land in Hyderabad,” said Sriram.
