On why he decided to produce Thanga Meengal, he said "Aamir Khan's 'Taare Zameen Par (2007) had inspired me to take up a film on a social issue and that is when Ram presented me with the beautiful script," said the director. He also added that it was he who forced Ram to do the central character as Gautham felt that only Ram can understand the complete nuances of the script.
The film stars Ram, Sadhana, Sally, Padmapriya and Rohini. Yuvan Shankar Raja has again collaborated with Ram after Katradhu Thamizh. Arabind Sara is handling the camera and Sreekar Prasad is editing the film.
