Filmmaker Vikram Bhatt who directed horror flicks like "Raaz", "1920" and "Shaapit" has taken his fascination to a new level by making his next scary drama in the 3D format. He openly admits that 'Haunted' is his most challenging film.

"Haunted is my most challenging and fulfilling film. The challenge began from the scripting stage itself because we had to visualize the country's first next generation stereoscopic 3D film. It was all new. The style was new and the technology was new.

"We had to acquaint ourselves with the technology, learn it, to adapt it. That was a major feat and I must thank the entire technical team. We would never have been able to achieve this unique milestone in Indian cinema without them, " Bhatt told reporters here at the launch of the first look of the film.

The film is slated to release April 15 and stars Mahakshay Chakraborty, actor Mithun Chakraborty's son along with newcomer Tia Bajpai. The technical crew of "Haunted" comprises of Brent Robinson, Christan Jeams, Cassidey and Michael Reuben Flax.

Set in the mountains of Dalhousie, "Haunted" revolves around a sprawling mansion with a secret past and a haunted present.

However, even though he is known for making horror films, Bhatt, who has 26 films to his credit, revealed that he gets scared at the drop of a hat.

"I get scared very easily. I feel a person who doesn't get scared can't scare anyone because if you can't feel something, you can't fake it, " he said.

The first Indian 3D film was the Malayalam film "My Dear Kutty Chetan" in 1984, dubbed in Hindi as "Chhota Chetan". Shot in 2d, it was converted to 3D and used an early version of 3D viewing technology. The first 3D horror film produced in a similar manner was "Saamri" in 1985.
