Prior to the shoot, the makers chose to film a promotional teaser featuring Silambarasan, Hansika Motwani, Santhanam and VTV Ganesh. The cinematographer Shakthi and photographer Venket Ram were involved in the making of the teaser in Taramani during May 2012. The film's first teaser was subsequently released on 6 June 2012, with an initial release date of Diwali 2012 announced. On the same day, the team began their first schedule with Silambarasan and Hansika Motwani in Chennai, with large crowds of onlookers observing the team during a shoot in Triplicane. For a particular set of the lead character's home in the film, three different locations in Chennai were combined to show a single spot. A house near Pachaiyappa's College campus, Aachi house in T Nagar and a house in Royapettah were represented as a single building. The film's art director, Ilaiyaraaja also organised sets to be designed in Ayanavaram and Perambur, to depict a railway backdrop. A wedding scene of Hansika's friend was also then shot on the campus of Panimalar Engineering College during June 2012. The team moved to Mumbai to film scenes in August 2012, and the director and editor re-worked scenes as the shoot progressed. A second schedule began in Hyderabad later that month, with Silambarasan working on the film alongside his commitments to finish Podaa Podi (2012). As Podaa Podi had been in production since 2008, Silambarasan opted to prioritise finishing that venture and Vaalu was temporarily put on hold.
