Pre-production period is the most time-consuming and very important period in film production. We have a very important unit – information and methodological group. This group selects materials and information required for work at any film. Jointly with production team we explore the locales and periods of the play, define distinctions of the film acoustic arrangement. Compulsory staging is performed prior to starting shooting: all hardware is tested, test shooting is performed, possibility for free movement of the camera is tested, etc. During helicopter shooting our specialists install a special unit for camera and pay special attention to safety precautions. Filming period is the most important and crucial stage in film production. If nothing was lost sight of at pre-production stage and every minute was planned, the film crew works as well as a smoothly running mechanism.
