The film stars Payal Rajput, Chaitanya Krishna, Veena Sunder, and Ananda Chakrapani.

The film is a remake of the director's own Kannada film Aa Karaala Ratri (2018), which itself is based on a Kannada play by Mohan Habbu translated from the English play Lithuania by Rupert Brooke.

[3] Thadhagath Pathi of The Times of India gave 2 stars out of 5 and wrote that "Anaganaga O Atihidhi is sadly a thriller with many loopholes in it, but with a better script they could’ve been overlooked.

This remake is a case of wasted opportunity with many beats of the original lost in translation.
