Alhough the movie has no songs, a separate soundtrack album of the movie was released to promote the movie - a first for a Hindi-language Bollywood film. This, however, did not work, and the soundtrack sales were disappointing despite the success of the movie.

The film broke several rules of Bollywood formula films and was nonetheless successful. There were no songs, it was only two hours long, it was heroine-centered, and it was a horror story, not a love story.

Abhishek Bachchan was earlier offered the role of Fardeen Khan but he opted out as his schedule was clashing with LOC 2003.

Rekha, Urmila Matondkar (as a child actor) and Victor Banerjee were in Kalyug 22 years before the release of this movie.

The movie had quite many similarities with Ramgopal Verma's earlier film Raat (1992): The lead actress being possessed, the theater scene, a brutal murder by twisting neck, creepy old lady in the neighboring house, psychiatrist trying to help the family, domestic help suggests about past incidents in the house, spirit of a deceased person still lingering in the house, tantric being brought to help and conflict between psychiatrist and tantric.
