When the film was launched, it was reported to be a remake of the 1969 film of the same title. However, it was revealed later that it was only inspired by the original. While the 1969 film was produced by B.R. Chopra and directed by Yash Chopra, the adaptation was directed by Abhay Chopra - B.R. Chopra's grandson, Yash Chopra's grandnephew, and Ravi Chopra's son. Ravi Chopra was an Assistant Director in the original film. This was Abhay Chopra's directorial debut.
The makers of the film shot more than one climax for it. Only the director, producers, and actors knew which version of the climax was used in the final cut. This was done to keep the suspenseful climax a secret. The makers launched a "Say no to spoilers" campaign asking the audience to not reveal the climax to others.
The film had a unique marketing strategy. The producers decided to do away with media interviews and appearances on reality shows for it. They relied solely on radio, TV, and print promotions. This was done in order to avoid the film's cast and crew having to reveal any details about the film.
This was a songless film like the predecessor that inspired it. A song was recorded to promote the film but did not feature in it.
Ittefaq Se (Raat Baaki) - This was the recreated version of the Hindi film song "Raat Baaki Baat Baaki" ("Namak Halaal", 1982) composed by Bappi Lahiri, sung by Asha Bhosle and Bappi Lahiri, and written by Anjaan.
