The film stars Kamal Haasan, Jayaram, Ramesh Aravind, Sriman, Yugi Sethu, Simran and Ramya Krishnan, with Urvashi, Aishwarya, Sanghavi, Vidhya Venkatesh, Devayani and Nagesh in supporting roles.

Ram's four closest friends, Ayyapan Nair, Vedhantham Iyer alias Vedham, Ganesh Hegde, and Hanumanth Reddy, attend their wedding reception.

Panicking, Nair, Vedham, Hegde, and Reddy decide to discreetly dispose of the body in spite of Ram's pleas to call the police.

They manage to roll the body in a blanket, dispose of it in a dry river and drive back to Chennai to return to their normal lives.

A few days later, the friends get very nervous when they learn of a news article regarding the discovery of a corpse in the same area where they disposed of Maggie's body.

Though recordings had taken place, Thenappan became apprehensive of the budget and chose to make a smaller-budget film, meaning Deva replaced Rahman.

Krishnamachari Srikkanth and Maadhu Balaji were considered to portray the role of Vedhantham Iyengar, before Yugi Sethu was finalised.

[7][8] Sethu signed on revealing that Kamal Haasan had approached him to be a part of his two previous films, Thenali (2000) and Pammal K. Sambandam (2002) too, which he did not take up.

[11] The film faced trouble during censorship and parts of a song featuring Ramya Krishnan were subsequently cut.

Malathi Rangarajan from The Hindu said that Crazy Mohan's dialogue was "the mainstay", describing the film as "completely entertaining".

She also praised the film's performances claiming that "with suitable slapstick, apt body language and timing and modulation that tickle, the veteran (Kamal Haasan) makes a mark yet again.

"[16] Furthermore, reviewers from Screen magazine dubbed the film as a "clean comic-entertainer", adding that Ravikumar "deserves a pat for weaving out a good screenplay based on Kamal Haasan's story idea and creating a laugh riot".

[18] Visual Dasan of Kalki felt Jayaram's talent was underused, and gave the film an "average" verdict.
