Director Thiru says he's not nervous about releasing Tamil thriller Naan Sigappu Manithan alongside superstar Rajinikanth-starrer Kochadaiiyaan on April 11. As of now, he is only concerned about completing the film before the release date. "I'm not going to compete with any film and nor am I nervous to release my film with Kochadaiiyaan. I'm only bothered about handing over the first copy of my film to my producers in advance. I'm only concerned about finishing the film on time," Thiru said. "Moreover, my producers zeroed in on the release date even before the makers of 'Kochadaiiyaan' did. Therefore, I always worked keeping in mind the release date and not worried about which film will I have to compete with," he added. Jointly produced by Disney UTV and Vishal Film Factory, Naan Sigappu Manithan features Vishal Krishna and Lakshmi Menon in lead roles. Thiru says working towards a deadline kept him engaged. "My last film got delayed due to several reasons. I struggled to see it release in cinemas. It was nice for a change to be working against a deadline. Working towards a scheduled release date kept me on my toes throughout," he said. Naan Sigappu Manithan also features Iniya, Saranya Ponvannan, Jayaprakash and Jagan in important roles. It's the story of a man suffering from narcolepsy, a neurological sleeping disorder.
