Oru Naal Varum

Gopi Krishnan, his wife, Rajalakshmi, and daughter, Dhanya, are enjoying their moments at Kutralam Waterfalls. Soon it is revealed that Gopi Krishnan is a corrupt assistant town planner using a government vehicle to come on holiday in Tamil Nadu during his duty hours. As his driver takes him back to his station in Kerala, he has an altercation with Sukumaran whose identity and profession are not yet revealed.

Sukumaran lives in a rented flat with his daughter. There is also a subplot involving the child custody battle between Nandhakumar and his wife, Meera. Later, Sukumaran is seen at the town planning office trying to get a building permit, and meets Vasudevan, who is also having difficulty with building permits. In reality, Sukumaran is in disguise and is actually a vigilance officer named Nandhakumar trying to arrest Gopi Krishnan in a corruption case.

Nandhakumar makes three attempts to get evidence against Gopi Krishnan. The first two failed because Nandhakumar's subordinate, Sunny, leaked the plans to Gopi Krishnan. Vasudevan commits suicide after the first failure. Finally, after catching Sunny, the third attempt succeeds, though there is confusion over the evidence, and some thugs attempt to murder Gopi Krishnan while he is in police custody.

However, Nandhakumar loses his court case against his wife and has to give up his daughter. Faced with the collapse of his corrupt life, Gopi Krishnan agrees to work with Nandhakumar to root out corrupt real estate developers. Meera returns Nandhakumar's daughter to him, saying that she could not handle her crying for her father all the time.

The film was produced by Maniyanpilla Raju under the company Maniyanpilla Raju Productions. Including print and publicity, the film costs around ₹4.35 crore to make.^[1] Oru Naal Varum was the maiden film of Sameera Reddy in the Malayalam cinema.^[2]

The film features songs composed by M. G. Sreekumar, with lyrics by Murukan Kattakada .^[3]

The film was originally planned to be released on 7 May 2010 and was censored by the Central Board of Film Certification on 7 April 2010. But it was delayed by two months due to a strike in the Malayalam film industry. The film was released on 9 July 2010.^[1]

The Indian Express wrote that "the plot is well-constructed and the element of satire well worked out. The film retains the interest of the audience till the end".^[1] Sify called the film "above average" and said: "Oru Naal Varum handles a relevant issue, but the problem here is the way it has been told. Of course, even in its current shape, the film is really good when compared to the rest of the movies that are being churned out in Malayalam these days".^[4] Rediff.com rated 2 out of 5 and stated that "The first half works wonderfully due to the presence of a lively and humorous Mohanlal. Sadly, he transforms into somebody else just before intermission: as if to do justice to his superstar image ... Oru Naal Varum may be a well intended social satire but it ends up as a conundrum".^[5]
