It was reported earlier Bollywood actress Prachi Desai was roped in for the female lead, but she has recently opted out of the film Thadaiyara Thaakka stating some reason. Source claim that Arun Vijay is said to have selected Mamta Mohandas for the movie. Rakul Preet Singh will appear in the role of an other leading lady.
However, Mamta Mohandas debuted in the Tamil films through director Karu Pazhaniappan film Sivappathigaram in 2006. Later, the Mallu star has also acted in Tamil film Guru En Aalu in 2008. After a break, she is returning to Kollywood with the movie Thadaiyara Thaakka, which will be her third film in Tamil.
