Malaysian Tamil actress Shasha Sri who had done small roles in films like Kanden Kadhalai and Paiyaa accepted to play the role a 'bubbly village belle' opposite Soori. In a significant change, Soori was signed on to replace Sathish in the supporting role and subsequently the team chose to rename the film as Oru Oorla Rendu Raja, to make most of Soori's presence in the venture. The team had revealed that they had registered two potential titles for the film, Sakkarai and Kaadhal Konjam Kammi, but opted to go with the latter as they felt the former may have created confusion with a Tamil film that had released earlier, Sakkarakatti (2008). Filming started in December 2013 on a train, with a photo shoot also being held with the three actors. Later in that month, Priya Anand was signed on to play an 'educated girl who hails from Madurai', with Sathish also added to the cast. Kannan revealed that the film will have a rural background with Vimal playing an educated youth from a farming family and the troubles he gets into due to his energetic nature.

In early November 2013, Kannan announced that his next venture would feature Vimal in the lead role and would be produced by S. Kannan was approached to direct Vallavanukku Pullum Aayudham, but Kannan opted out of the film as he was unhappy on first copy production agreement, he then announced that his next directorial would have Karthi in lead role titled 'Alangaram' but the project got shelved.

After the film's release, one of the most fatal incidents due to oversight in the industrial safety measures happened at Ranipet Sipcot industrial estate in Vellore district when a tank of an effluent treatment plant collapsed on the compound wall of an adjacent factory where the employees were present. It was a noble effort by Kannan to have raised an awareness and caution to incorporate safety standards in order to avoid any untoward incident that may harm the laborers' lives and lifestyle through this film. The story is centered on a factory in Kayalpattinam (Thoothukudi) which explores the safety of laborers in factories being at jeopardy. How Azhagu and Mike help Priya escape the goons and whether they help her win the case forms the rest of the story. The case is being heard the next day, and if Priya makes it to court, the company will lose the case. Priya decides to sue the company and files a case against them. Priya begs the owners to dismantle the machine so that Kalpana can be saved, but the owners are reluctant, and Kalpana dies as a result. Back in the factory, Kalpana operates a costly machine and unfortunately gets her hand stuck in it, resulting in huge blood loss. However, Selva denies and insults Priya, who leaves the place. Priya gathers proof and talks with Selva to provide safety equipment to the workers so that no one gets affected further. Priya enters the company with the help of Kalpana, who works there. There, she learns that the people of that village are affected by potential cancer and other effects due to the steel factory owned by Selva Vinayagam ( Nassar). Priya had a friend named Kalpana ( Vishakha Singh), who was from a village where Priya went for a medical camp. Priya is saved by Azhagu from a man who tries to kill her. Azhagu falls for her immediately and decides that he should become an engineer so that he can marry her. Initially, they take Priya for a prostitute but later understand that she is a doctor. They meet Priya ( Priya Anand) in a train while trying to escape from a few goons who were chasing them for a reason. Azhagu ( Vimal) and Mike ( Soori) are thick friends and happy-go-lucky jobless youths who just roam around doing nothing.
