Apparently, the red contacts were suggested to build an aura of mystery around the film.
In fact, a similar pair was also sported by Hollywood actor Robert Pattinson for the Twilight series, where he played a vampire. Emraan says, “There is a certain element of mystery in the film and they wanted to show the same in the poster too.”
In fact, the actor also tells us that his co-stars Bipasha Basu and Esha Gupta were quite freaked out while shooting some of the spooky scenes for the film. He says, “The scenes were really scary! I am kind of immune to them as I watch a lot of horror films.”
