T. J. Gnanavel wrote the story after meeting Thenkachi Ko. Swaminathan, an orator.[2] Initially Gnanavel wrote the script with Nivin Pauly in mind for the role of protagonist; though he was interested in the script, due to non-availability of dates, the actor could not sign the project. When Ashok Selvan learned that the debut director Gnanavel was looking for protagonist through the music director Nivas K. Prasanna, he himself expressed his interest to the director and then Ashok Selvan and Priya Anand were signed in this project in early 2015 to play the lead roles in this college love story.[3][4] Prior to this, Gnanavel had written dialogues for Payanam and Raktha Charithiram.[5] The film began production during May 2015, most of the scenes were filmed at VIT University in Vellore.[6] Telugu actress Anisha Singh was signed for a role and this would be her debut in a Tamil film.[7] Priya Anand said that unlike most films which focus on "frontbenchers" who are seen as "over-achievers" and "backbenchers" who are usually the rebels, this film revolves around "people in the middle, which I think represents most of our population".[8]

The team filmed a promotional song called "Maatrangal Ondre Thaan Maarathada", featuring appearances from many leading actors from Tamil cinema. The song portrays that hope and belief are very important and everyone in this world are a gift to themselves.[9][10]
Earlier, the film was scheduled for theatrical release on 14 July 2017,[11][12] but was postponed by the producers to 28 July 2017.[13]Baradwaj Rangan wrote for Film Companion, "the director, who also wrote the film, keeps veering off into subplots that sound fine in theory but don't come together convincingly on screen. Had the events leading to this development been put in place much earlier, the film might have been more than just an easy watch."[14] M Suganth of The Times of India wrote, "In addition to being the story of an average guy and his success, Kootathil Oruthan tries to also be one about his romance. This results in the film losing some of its lightness and feel-goodness".[15]
