Bipasha had inhibitions about playing the ghost for the first time as she was not sure if she would be convincing enough for the role.
"There was no benchmark for me in terms of playing this role. I had not done something like this before. As an actress, you are used to looking good but here I had to snarl and contort my face. So I was not sure about doing it properly. After every shot, I would look to my director for assurance," she said.
The actress is sharing screen space with TV actor Karan Singh Grover, who is making his Bollywood debut with the film.
Bipasha said she is happy the two share a good on-screen chemistry.
"Karan is a very talented actor and a great co-star. I wanted a co-actor, who would look really good with me on-screen and who can emote well because the love story forms the basis of the film.
"Karan and I are very similar in real life. He and Bhushan have become close to me now. I did not have any hangups about acting with a newcomer and I have done in the past too. I am not a difficult actor to work with.
