The film was produced by Shankar Thiyagarajan of Ascii Media Hut, for whom it is their debut production. Shankar stated he had the urge to do something experimental and pitched the idea of a horror anthology to various film-makers, eventually getting thirty young story writers who were interested. They then shortlisted five, and with Shankar's own film, it became six short films.^[3] In addition, for most of the directors, it is their debut film, with the exception of Cable Sankar who had previously directed the film, Thottal Thodarum (2015). Ajayan Bala also has experience in the industry, having written the screenplay for films such as Chennaiyil Oru Naal (2013) and Manithan (2016). Shankar Thiyagaran initially titled the film Hexa, with the tagline of 6 Athiyayam, but later made the tagline the title.^[3]
