Despite reports that Shilpa Shetty was added to the cast in February 1999, it was later clarified to be untrue. Laila, who had made her acting debut earlier in the year with Kallazhagar, was signed on to portray the role planned with Shetty instead. Originally, her role was supposed to feature throughout the film, but Shankar shortened her character, owing to her call sheet problems. Renowned muralist Natanam and Kalairani were cast as Arjun's parents. S. Sashikanth, who went on to produce films like Thamizh Padam (2010) and Kaaviya Thalaivan (2014), and K. R. Mathivaanan, who directed Aridhu Aridhu (2010), worked as assistant directors. Filming The film was jointly launched by S. Shankar and his co-director R. Madhesh in October 1998 at an event attended by actors and technicians from the Tamil film industry, with actors Rajinikanth and Kamal Haasan being the special invitees. Production continued for several months, with reports suggesting that the film was delayed due to Manisha Koirala's unavailability though Shankar later stressed the production work demanded such delay. Parts of the film were also shot in Bikaner, Rajasthan while the team also shot extensively in rural Tamil Nadu. The film's cinematographer Anand later noted that the scenes involving crowds shot on Anna Salai, Chennai were among the hardest and most satisfying scenes he had worked on. The song "Shakalaka Baby" was the last song to be shot, with Sushmita Sen selected to feature in a special appearance for the song. Stunt master Peter Hein revealed that he worked as a body double for Arjun in the scene where he had to run nude on the streets. Themes and influences The film dealt with the theme of a television cameraman who is forced to take over the duty of Chief Minister for one day. It also dealt with the concept of opportunities for educated people in politics and demonstrated it is possible to bring change in the country. The film's basic idea was inspired from Nixon-Frost interviews which were broadcast in 1977 and also inspired by Indian actor Sivaji Ganesan being named the honorary mayor of Niagara Falls, New York for one day during his visit to the United States. Soundtrack The soundtrack features six songs composed by A. R. Rahman and lyrics penned by Vairamuthu. The song "Shakalaka Baby" was re-edited by A. R. Rahman and featured on the international musical production Bombay Dreams, which ran
