The movie, slated to release Sep 12, is a creature-based thriller directed by Vikram Bhatt.
In the film, Bipasha's character Ahaana battles a creature, based on Indian mythology, as she transforms from a "vulnerable and lonely" girl to a powerful woman.
"It is India's first creature-feature. For an actor is all about reacting to a situation and who is in front of you. But for the first time there was no one in front of us so we had to imagine everything.
"Shooting part was extremely difficult for the actors and the technicians. I hope we being Indians support the film because of the efforts put in by Indian technicians. The creativity is indigenous and the team is Indian, no foreigners," Bipasha told reporters here.
"They were shooting with 3 D cameras which was completely different from the normal process and post that there was 11 months of post-production where the creature was actually made.
"Every scale, every speck of saliva of the creature was imagined and created by Indian technicians... no foreigners," Bipasha explained.
The storyline, she said B, is India-centric and based on the concept of Brahma-Rakshas or demon spirits of Hindu mythology but if one were to consider the creature-generated from special effects-in isolation, the beast is much like those in the West (ern films).
"I will not compare the film as a whole, with the West, because the sensibilities are very different. The story line is India-centric but just the creature is very much like the West," she said.
