Mani Ratnam wanted to shoot some scenes for Kadal at a church in Tuticorin but the local people in the area were hesitant. Finally, the veteran director decided to seek the help of his art director and an exact looking set was erected nearby.
The director had shot some important love scenes with Karthik’s son Gautham and Samantha here. Soon after the shooting was wrapped up, Mani Ratnam did not want this church set to be razed down and instructed his men not to demolish it. The team had left the place with the church still intact.
