<span class=normal>Pre-production, is fundamental in defining the overall vision of the film and making sure that the performance is delivered in harmony to that vision. It is critically important to make the best use of time available at hand in designing and planning out a film, working on the script and the pre-production phase. Bejoy says, The idea initially was to do something based on a true incident, inching towards the Adnan Patrawala case. This made me want to do a kidnap kind of a thriller because it excited me. During the screenplay phase of pre-production, we latched on to true incidents through police records and tried to incorporate them into the screenplay. I had an excellent direction and production team in place, even though it was a low-budgeted film. The guys were very technically sound. Although the film kept on stalling at different places, this gave us more time for working on pre-production process right from casting, location, procuring special equipment etc. While the film was in constant development for over one and a half years, the pre-production phase took us a good six months to accomplish. <br><br><br><p class=clear>&nbsp;</p>For executing some of the avant-garde point of view scenes in the film, Bejoy was required to procure special cameras and rigs for Shaitan. I knew this was very treatment heavy film, I always allocate a certain amount of the budget for special equipment that would be used in the films production. We already had a notion on how we were going to shoot some of the shots, for which we planned and did a thorough design in execution. I made sure that we had the right technical equipment and technicians on board to help us achieve this. In all, there were three cameras put to use, apart from the Red Camera that was used for the principal photography, we also employed the 7D and the Weisscam. Shooting in 7D gave us the freedom and flexibility in taking some very unusual shots, explains Bejoy. </span>
