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.
Vivek was selected to perform comedy portions though he was later replaced by Thambi Ramaiah. 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). 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". ==Soundtrack==
