"The script for both Tamil and Hindi version is locked. I'm also roping in a Tamil actor to play the main antagonist. We will start shooting by January end in Prague, and we will shoot in both the languages simultaneously," Saif told IANS.
While the Hindi version is titled "Shraap", the film is titled "Saapam" in Tamil.
The makers unveiled the first look poster of the film on Thursday to ring in Kavita's birthday.
According to Saif, the film will be boldest and scariest horror film in Indian cinema's history.
Produced by Neelam Sharma under the banner Neelam Sharma Entertainment, the makers plan to release the film in August next year.ALSO READ: Review: 'Apurva' has Tara Sutaria asking filmmakers to take notice as she delivers a stellar act
