Not only does Vishal Bhardwaj Productions and Balaji Motion Pictures come out with films which are different in nature, but each time one of its films is being geared up for release, the production house comes out with an innovate kind of promotion. A similar kind of thing happened recently when the trailer of their forthcoming film <em>Ek Thi Daayan</em> was launched at a unique, first-of-its-kind themed event at Mumbai's Film City.
