Stalin had convinced the
actress of that film, Nayantara, to meet Pandiraj.
Subsequently, Nayantara signed on to be a part of the film
during November 2013, agreeing to work with Silambarasan for
the first time since their break-up, with the news creating
increased hype around the project. Pandiraj began casting
for a second lead actress during the middle of 2014 and held
discussions with Bindu Madhavi and Taapsee Pannu, before
finalising on Andrea Jeremiah.
The project first ran into production troubles during July
2014, when Silambarasan had changed his hairstyle in between
schedule breaks, leaving Pandiraj unhappy. Silambarasan
subsequently disclosed to the media that Idhu Namma Aalu was
his production and that others should not question his
involvement in the project.
