Thandavam is a 2002 Indian Malayalam-language action film directed by Shaji Kailas, written by S. Suresh Babu, and produced by Johny Sagariga. It stars Mohanlal, Kiran Rathod, Nedumudi Venu, Captain Raju, Saikumar, Manoj K. Jayan, and Jagadish. Released in 86 centers, Thandavam had the highest opening-day collection at the box office in the history of Malayalam cinema, although it failed to maintain it further. The film was dubbed into Tamil and released as Erumugam.


The story centers on Kasinathan, a pragmatic but playful businessman keen on general welfare of his men, and also running a resort and massage parlour as a side business. Kasinathan is the younger brother of Swaminathan, the heir to Valiyamangalam Malika and the head of erstwhile feudal Midhilapuri. Midhilapuri is an idyllic village prospered through judicious use of agriculture as the path to good life. Kasinathan is powerful in his own right and is tipped to succeed influential politician Menon in Kerala politics. Kasinathan has a secret admirer in the form of a mysterious girl who drops messages and love hints every day. But Kasinathan has still better issues to worry about!.
