The announcement attracts numerous potential brides and grooms, who are interviewed by Gnanapithan (K. Bhagyaraj) and Arivozhimangai (Urvashi), or by doctors Mithrabuthan (Janagaraj) and Panchabootham (Senthil).

Kuselan, Suseela, and Krishna are happy upon thinking that everything would happen as planned, but there is a major hitch that they did not know about: most of the children have already fallen in love.

Easwari, Uma, Aishwarya, and Hema are in love with Kanna (Prabhu Deva), Pallavan (Pandiarajan), Gautham (Vineeth), and Kanthen (Livingston), respectively.

Urvashi is paired with the absent-minded Dr. Ram Kumar (Karthik), who mistakenly believes the interview is for a medical position.

The plot takes a twist when Kabilan (Mansoor Ali Khan), with his accomplice Vichitra (Vichithra), attempts to pose as a groom but fails.

In the final revelation, Kuselan confesses that his heart attack was a ruse, and his true intention was to ensure that his children got married.

In order of appearance: Sons: Daughters: Love interests and spouses: Supporting roles: Producer Giridharilal Nagpal announced his intentions of making Suyamvaram, a film shot within 24 hours, in January 1999, stating it had been a fourteen-year dream.

The film's launch event was held in the same month on 24 January 1999, with prominent actors Rajinikanth and Kamal Haasan attending.

Additionally, actresses Simran, Devayani and Keerthi Reddy, along with directors R. K. Selvamani and S. A. Chandrasekhar, were no longer part of the film.

[8] Nagpal outlined his ambitious plan: the entire filmmaking process—including shooting, developing rushes, editing, dubbing, re-recording, and final mixing—was to be completed within 24 hours.

By 6:30 PM, the entire crew gathered at the Vijaya Vauhini Studios, which had been transformed to resemble a wedding hall, for the final scenes.

[4] At the same time, Vineeth refused to shoot a scene in which his character was locked in a bathroom, causing additional delays as the directors attempted to convince him to continue.

[10] Costume designer S. V. Kumar worked with forty assistants, and dance choreographer Lalita Mani contributed to the film's musical sequences.

[20] D. S. Ramanujam of The Hindu wrote the film is "not only a fairly humorous entertainer but an example of how the artistes and technicians of Tamil filmdom can co-operate wholeheartedly, put their heart and soul, complete a movie in just 24 hours and earn a place in the Guinness Book of Records".
