Thirukumaran is a carefree, laid-back guy who has a great time with his friends. He falls in love with Priya, who is the sister of Guru, a rich business tycoon. The story is about a cat-and-mouse game between Thiru and Guru, who is against Thiru and Priya's love. Thiru wins the game at the end.
The film was announced in late August 2005 with Boopathy Pandian and Dhanush coming together after a previous collaboration in Devathayai Kanden. Pandian had previously discussed the role with Bharath, but the actor's refusal meant that Dhanush was chosen. Shriya Saran, who rose to fame in Tamil films after her role in Mazhai, was signed as the heroine and the film was titled as Naveena Thiruvilayadal, though the prefix was later dropped. The following September, actor Sivaji Ganesan's Fan Club requested the film's producer, Vimala Geetha, to change the name of the film Thiruvilayadal. They had felt that the title was reminiscent of Ganesan's 1965 film of the same name, and felt that the new venture would defame the old film. K. Bhagyaraj was initially pencilled in to play Dhanush's father in the film, but was later replaced by Mouli due to the delay of the film. Shriya Saran was forced to opt out of the film in October 2005 owing to her commitment to work in Rajinikanth's Sivaji. Reports suggested that either Tamannaah or Ileana may be approached to replace her, while the film's inactivity led to rumours that the film was cancelled. However, in January 2006, Boopathy Pandian confirmed that the film would continue and the remaining portions would be swiftly completed. Shriya however returned to work on the film after she was able to allot dates.
Release
The film opened in December 2006. Rediff.com noted that "Director Boopathy Pandian has a looser hold on pacing, ensuring that the interest never flags", adding that "the real reason to watch Thiruvilaiyadal Aarambam is Dhanush, who epitomises the new age hero: he is no superman, he is not even close to perfect, and he is thoroughly unapologetic about it all." Another critic from Indiaglitz mentioned that "Bhoopathy Pandian has a fair grasp of what makes an entertainer click with the comedy. His simple handling of an easy subject sees it through." Sify cited that "Dhanush as the hyperactive Thiru is simply superb and his ability to deliver funny lines casually is uncommendable. Prakash Raj does his role to perfection, while Shriya looks good and her costumes are fabulous." The film grossed in Tamil Nadu - the highest grosser for actor Dhanush at that time. Post-release after being offended by a remark in the film, Bank of Baroda contemplated taking action against the film by trolling their bank name which ultimately spoils their bank's name.
Remakes
In 2007, the film was remade as Takkari. It was also remade and released in Kannada as Dhool in 2011, with Prakash Raj reprising his role. Furthermore, it was then remade and released in Bengali as Idiot in 2012, and in Oriya as Rangila Toka. It was also remade in Bangladeshi Bengali as Daring Lover. The movie was uncredited remade in Burmese as Chocolate Baby.
Soundtrack
The soundtrack of the film was composed by D. Imman and won good reviews upon release in 13 October 2006. The lyrics were penned by Vairamuthu, Na. Muthukumar, Viveka and Thiraivannan. The soundtrack also features a remixed version of the song "Ennama Kannu" from Mr. Bharath.
