After the moderate success of their previous collaboration Ellam Avan Seyal (2008), Shaji Kailas and RK announced their second collaboration in 2011 with the project titled Kadamai Kanniyam Kattupaadu named after a 1985 film of the same name produced by Kamal Haasan.[2]Vivek was selected to perform comedy portions though he was later replaced by Thambi Ramaiah.[3] However, the film was further delayed and remained unreleased. The film was then resurfaced under the title Eepeeko but later changed as En Vazhi Thani Vazhi named after the dialogue spoken by Rajinikanth for Padayappa (1999).[4] RK said: "It's the story of a police officer who deals with the criminals in his own way. Hence we felt the title was very relevant t the story. It does add some weightage because it's a popular dialogue, but eventually it's the film that matters".[5]
Soundtrack
The soundtrack was composed by Srikanth Deva, while the lyrics for the songs were written by Vairamuthu and Ilayakamban. The audio was launched on 16 December 2014 by actor Vijay at RKV studios.[6]
The film was released on 6 March 2015 with 10 other Tamil films.[7] M. Suganth of The Times of India gave the film a rating of one out of five stars and said that "En Vazhi Thani Vazhi is that kind of film but by the time it ends, all that we feel is murderous rage — for it not only manages to sink below the bar but digs a pit, and keeps going deeper and deeper into the ground".[8][9]
