Udhayanidhi Stalin had bought the distribution rights of Rajeshs previous film Boss Engira Bhaskaran. As the film emerged successful, Udhayanidhi decided to continue the collaboration, going on to play the lead role in the new project.During the preproduction stage, several actresses including Asin Thottumkal and Nayantara were approached to play the female lead but Hansika Motwani was eventually signed. The protagonist was revealed to be an unemployed youngster, as unofficial reports of a ticket collector and a band master were brushed aside. Arya, Sneha and Andrea Jeremiah were roped in to perform cameo roles. Hansika was forced to learn Tamil, for the director wanted her to speak fluently in the film. Rajesh planned to retain the same crew members from his first two ventures but since Udhayanidhi wanted Harris Jayaraj to score the music for his debut film, he was signed over Rajeshs usual associate Yuvan Shankar Raja, while the makers decided to proceed with Balasubramaniam as the cinematographer as Sakthi Saravanan was unavailable. ........
