Development Screenwriter
Shagufta Rafiq stated in an interview that the story is based on
Sant Kabir's idiom, "
Bura jo dekhan main chala, Bura na milya koi; Jo dil khoja apna, Ta mujh sa bura na koi", which means that the evil is within oneself and that is the message of the film.
Vikram Bhatt (who was the original
Raaz director) was replaced by
Mohit Suri. Suri had reportedly added more dramatic space to the film and played around with visuals and sounds which led to an extraordinary pace. Suri was inspired after reading
Hindu mythology, where good and evil are represented in stark contrast. Multiple scenes in the film are borrowed from other horror films; the bathtub horror scenes and the well in the end are similar to
The Ring, the scene where a man is found inside the hidden roof floor of a house is similar to
The Grudge, the future prediction, plot, the road accident with the wild bulls and various other sequences were taken from films such as
Final Destination,
Mirrors and the TV series
Heroes. Reportedly, the main secret revealed in the climax was inspired from the 2000 American film
Erin Brockovich where the female lead also investigates the water of an area getting contaminated due to a nearby Energy and Gas plant.
Casting Kangana Ranaut replaced
Bipasha Basu as the female lead, playing Nandita, a supermodel.
Amrita Rao was offered the role, but declined. To prepare for the role, Ranaut had to reportedly undergo many different looks and even changed her hair colour to red.
Emraan Hashmi was cast as Prithvi, a painter with no contact to the outside world, replacing
Dino Morea as the male lead. According to the actor, though comparisons are evident with
Raaz (2002), this film has a different plot and will give a new definition to the horror genre. Dino Morea expressed his disappointment with the decision saying "I'm not disappointed but definitely baffled. How can they make a
Raaz 2 without anyone from the original cast? How can it be a sequel, then?".
Adhyayan Suman plays Yash, a documentary filmmaker who is perceived as an atheist and believes in scientific rationale behind everything. His beliefs are challenged in the film. He reportedly called this film his debut, despite debuting in the
Haal-e-dil (2008).
Sonal Chauhan was reportedly offered Kangana's role which she declined.
Jackie Shroff was reported to be playing Kangana's father, which after the release was revealed to be Emraan's father.
Filming Filming began in June 2008 in
Shimla. Some parts of filming took place in
Mumbai. Kangana was paid 6 million for her role in the film. The film received an A certificate from the
Censor Board of Film Certification.
Mukesh Bhatt however denied these claims stating the film received a U/A certificate. Filming completed on 10 November 2008 in Mumbai.
Sushant Singh Rajput assisted director
Mohit Suri during the making of the film.
Promotion The teaser trailer was released by Hashmi in November 2008 alongside the film
Fashion.
Sony BMG partnered with social networking site
Ibibo to launch a website for the film. The RTMC application allowed Ibibo members to participate in a movie making contest where the winner got the chance to spend a day with Mohit Suri, and learn the art of filmmaking from him. Ashish Kashyap, the CEO of Ibibo, said, "The Raaz – The Mystery Continues application on Ibibo reiterates our core value proposition to recognize talent and enable users to self express and engage with latest Bollywood content. This is a perfect example of a Bollywood movie promotion leveraging the power of social media on Ibibo". The theatrical trailer was released alongside
Ghajini and
Rab Ne Bana Di Jodi. Kangana Ranaut and Emraan Hashmi initially did not participate in promotions. However, the entire cast, including Hashmi and Ranaut, later appeared for the promotions in
Bangalore. ==Reception==
