Produced by Suresh Balaje and George Pius, the film was simultaneously shot in Hindi as 13B: Fear Has a New Address with a slightly different cast.

[6] A web series with a similar theme called Dhootha written and directed by Vikram Kumar was released in 2023.

They encounter a series of small, but strange, incidents, which are regarded as inauspicious by his family but shrugged off by Mano.

The women in the family get hooked on a new TV show, Yavarum Nalam (Everyone is Well) / Sab Khairiyat (Hindi version)).

Priya is saved by their longtime family friend and doctor, Dr. Balram aka Balu / Dr. Shinde.

To his horror, he discovers that Yavarum Nalam / Sab Khairiyat is a different TV show -- the serial that his family watches appears only in his house, every day, at 1 p.m/13:00.

Back at home, Mano finds an album with photographs of the family from the serial, as well as one man he doesn't recognize.

Mano, along with his Inspector friend Shiva, meet Chitra's former fiancé, Ramachandran / Ram Charan (Hindi version), a High Court defense lawyer who tried to plead for Senthil's innocence.

He goes to the hall and witnesses the climax of Yavarum Nalam when they are showing the murderer's identity: Mano's face is shown as the killer.

They bring Senthil/Ashok (Hindi version) home, and the apartment's lift finally works for Manohar, while Priya becomes pregnant again.

Here he teamed up with cinematographer P. C. Sreeram, editor Sreekar Prasad, sound designer A. S. Lakshminarayanan and art director Sameer Chanda, who also happen to be National Film Award winners.

[7] Esha Deol and Kareena Kapoor were originally considered for the lead role which eventually went to Neetu Chandra.

Veteran Marathi actor Sachin Khedekar, who made his debut in Tamil cinema with Yaavarum Nalam, took great effort in learning his lines.

A temporary shooting floor was created from scratch in Egmore, Chennai, inside which an elaborate apartment set was erected.

Times of India gave the movie a 3.5/5 rating and said, "Watch out for some zippy cinematography, a stylized monochrome tint, and some snazzy editing.

"[10] Hindustan Times gave the movie 2 out of 5 stars and stated, "If you like horror films, this one's par for the course, especially in the first half, where Vikram K Kumar uses the TV set for an interesting premise, the actors do their bit and the camera picks up suitably weird angles.

"[11] Rediff.com rated the film 2 out of 5 stars and said, "One simply wishes it didn't have to be such hard work getting to the point, for the filmmakers as well as the audience.

"[14] Film Journal International wrote in their review, "J-horror-styled supernatural thriller from India doesn't have the gore or intensity of the real thing, and for many in the mainstream, that's a relief.
