Entirely shot inside a single room, the film stars Santhosh Prathap, Jayakumar, Aanchal Singh, Samaira Sandhu and Iraa Agarwal among others in leading roles.

Featuring music composed by Sathish Selvam, cinematography by A. Packiaraj and editing by R. Sudharsan, the film had a theatrical release on 24 March 2017.

The makers of Dhayam stated that it would be the first Indian film to be shot inside a single room from the start to the end, and that it about would be about eight people and an interview that changes their lives.

[4] The film's director, Kannan Rangaswamy, revealed that he had challenged himself to write a screenplay that happens inside a room, without making it seem like a stage play or television drama.

While writing, he noted that he had to ensure that he had to keep the screenplay "tight" in order to engage viewers and that he worked extensively on the set-up of the single room.

[5] Technicians including editor R. Sudharsan, and Cinematographer A. Packiaraj, an erstwhile assistant to Nirav Shah during the making of Billa (2007) and Sarvam (2009), was signed on to work in the project that was produced by Sundar.

Model Iraa Agarwal was signed on to play one of the leading roles after Kannan had been impressed with her portfolio, and had successfully convinced her to make her acting debut through the project.

Another model Samaira Sandhu also made her acting debut as one of the female leads with the film and completed shooting for her scenes in fifteen days, along with the other seven actors, by October 2015.

[7] The film's release was delayed for over a year as post-production work took place throughout 2016 and early 2017, with composer Sathish Selvam recording the background score with the assistance of a sixty-piece orchestra in Macedonia.

[11] Malini Mannath of The New Indian Express compared it to the psychological thrillers Identity, Exam, Cube, and The Island, saying that Dhayam is "for hardcore lovers of the genre".

[13] Indiaglitz.com's reviewer cited "go for it if you fancy a few thrilling moments and do not care too much about acting expertise, befuddling genre jumps and lip sync issues".
