Vijay Sethupathi announced that he signed the film in September 2013 in an interview to
The Hindu, under the direction of first time film maker
Ranjit Jeyakodi. Since Sethupathi had prior commitments, the film was supposed to take off only a year later. However, as
Sanguthevan, a project of Sethupathi was getting delayed, the team chose to begin
principal photography immediately, with the director telling that they had no time for
pre-production but started filming since he had a cinematographer and a music director ready.
Gayathrie was swiftly signed on to play a violin teacher in the film, and to practice for her character she began to learn the instrument part-time. The film was launched on 17 December 2013. After the first schedule which lasted for 26 days, 50 percent of the film had reportedly been completed. Filming was held across Chennai including at Fortis Healthcare, Vadapalani by mid-February. In June 2014, the director informed that "about 10 -12 days of shooting" was remaining. In October 2014, Telugu actress
Sonia Deepti also stated that she had a short role in the film. Following a period of delay, the film was sold to JSK Film Corporation in October 2016 and renamed from
Mellisai to
Puriyatha Puthir. Regarding the title change, Gayathrie said, "
Mellisai, even though we said it was a mystery thriller, the title may not have given the same impact. But [
Puriyatha Puthir] does it". The team prepared to launch the film in January 2017 but had to withdraw after financiers contested against debts taken up by Deepan Boopathy for another film,
Aakko. ==Soundtrack==
