Initially Anirudh Ravichander was approached to do the male lead, but later his role was replaced by Vijay Sethupathi.
All the songs of this film were written by the director Vignesh shivan and dialogues were not written for the film..only plot was there and everything was improvised on the set
It is the second movie of the director Vignesh Shivan.
Title for the movie is borrowed from Vadivelu 's famous dialogue in the movie Thalai Nagaram (2006) where he pretends to be a goon and so does the protagonist of Naanum Rowdy Thaan (2015).
During the end credits scene, Pandian (Vijay Sethupathi) tries to convince Kadhambari (Nayanthara) that he would be better off accepting a job as Police Officer instead of 'remaining a rowdy' and as the scene fades, he exclaims that he would look grand in a Police Uniform. Vijay Sethupathi's next release after Naanum Rowdydhaan was Sethupathi, in which he plays a Police Officer.
