The turn of the millennium saw Bollywood filmmakers try their hands at a relatively new genre: erotic thrillers. Mahesh and Mukesh Bhatt`s Vishesh Films was among the first production houses to exploit the genre in a big way. Vikram Bhatt started experimenting with `Kasoor` (2001) and aced the formula with `Raaz` (2002). He devised a formula that was to rule the box office for the next decade: Melodious music, titillating scenes and unapologetic approach during promotions. Though films like `Aastha` and `Kama Sutra: A Tale Of Love ` were made in the `90s, but they weren`t `erotic thrillers`. They were about exploring the other side of human nature, the desire to understand a person`s physical needs. Some of them went on to become established franchise like `Ragini MMS and `Hate Story`. The moment sustained and after eight years, `Hate Story` (2012) released in 1100 screens and earned more than Rs 12 crore. It was more than anybody could have asked for. The new-age filmmakers are willing to take chances. Pandya says, they can`t explain everything in the trailer. He makes commercial films and is fine with the `erotic` tag.
