Last seen in Oru Nalla Naal Paathu Solren, Ramesh Thilak is now officially a part of Viswasam. The RJ-turned-actor who rose to fame through his performance in Demonte Colony made his acting debut in Ajith's Mankatha in 2011. The self-proclaimed Ajith fan also played a cameo role in the Siva directorial Vedhalam. 

Since it has already been confirmed that Yogi Babu is also a part of the project, Viswasam marks the comeback of the hit comedy duo of Kaaka Muttai. The shooting of the film, which stars Nayanthara opposite Ajith for the third time, began on Monday in Hyderabad.
