As we watch the trailer of Naan Sigappu Manithan, there is one thing that makes it clear to all – Vishal has put his heart and soul into the project. Apparently, director Thiru shedding lights on this film says that it was really a speculative situation for Vishal all throughout the the production. Since he plays the role of a narcolepsy, he had to fall loosely on the roads, bridges and many other locations. Due to his great height, the actor had to hurt himself every time he fell down. “Soon after coming across the documentaries based on the lives of narcolepsy patients, I had met few doctors who suggested me to maintain a body language and Vishal had perfectly matched it.” Naan Sigappu Manithan is produced by Vishal under the banner of Vishal Film Factory and is released by UTV Motion Pictures. GV Prakash has composed songs and Lakshmi Menon stars opposite Vishal in female lead role. The film is scheduled for release on this Friday (April 11).
