The film 'Nungambakkam' is based on the 2016 sensational murder of a techie Swathi at Nungambakkam railway station by her stalker Ramkumar. The film initially titled Swathi Kolai Vazhakku has been renamed as Nungambakkam. The trailer of the film was launched yesterday by Vishal, director SA Chandrasekar and Arya in the film's trailer launch event.
