In between these, Varathachari, Paramasivam's friend who knows the reality comes home. After avoiding anything wrong, they encounter Janaki's maternal uncle, 'Security' Singaram. He is a very doubtful person who pressurize the youths, and starts suspecting them. Yet, he fails to convince his sister and brother-in-law. When Balamurugan is on the way, Paramasivam steps in to help them, without knowing the truth at all. He concocts a more complicated story, where Ramalingam is his son, Janaki and Sundaralingam reprising their real relationship and worse, V. Anand to be his cousin. Anand is actually Ananda Vikadanantha who is absconding. When more of this happens, the elders smell something fishy and everything falls onto Ramalingam's head. To put an end to all these, Sundari reveals the complete truth to everyone. Singaram tells all that Anand is the fraud and once again, Ramalingam has to prove his innocence. A chase ensues when V. Anand is held hostage by his ex-partner Junior Vikadanantha for money which he looted. Inspector Chokkalingam arrives in time to find Ananda Vikadanantha and Junior and Ramalingam is proven innocent. Paramasivam accepts Janaki and Sundaralingam, and Balamurugan is happy about Ramalingam and Sundari. "Kaathala Kaathala" was initially expected to be directed by K. S. Ravikumar who directed the successful "Avvai Shanmughi" with Kamal Haasan in the lead earlier, but he was later replaced by Singeetam Srinivasa Rao after he refused to sign the film until the FEFSI strike of 1997 had stopped. Actresses Meena and Simran's unavailability led to Rambha being cast in a lead role. Nagma also opted against signing the film fearing that a potential clash may arise with actress Rambha, after the pair's alleged fall out on the sets of "Janakiraman". After Soundarya's death in 2004, Kamal Haasan paid tribute by revealing that "she came forward to do the movie, when the rest of the industry was unwilling to work with me." "Kaathala Kaathala" was released on 10 April 1998. Namma Ooru Velan from "Indolink" gave the film a positive review, citing that "if one can put the inspirations behind, the movie is quite enjoyable" and that "the going gets very complicated and absolutely hilarious".
