On one hand while filmmakers are making all efforts to get the audience feedback about their films, on the other hand they are also worried that a trial show might risk that their plotlines are revealed much before it reaches the public domain.
In a move to curb the possibility of getting your plotlines revealed much before the film releases, the Indian filmmakers have taken a leaf out of Hollywood studios and have started following a Non Disclosure Agreement. The NDA means that if you watch a trial show of the film, you are bound not to talk about the film publicly or pass any opinion or judgment about it.
The NDA was implemented for the first time when 3 IDIOTS was recently screened for a select few in order to get their feedback. With this new measure in place, the Bollywood filmmakers have surely found a new way to protect their interests henceforth.
