The Production Supervisor communicates and mediates between many people on the film set and in the executive offices. This includes the Director, Producers, studio executives, assistant directors and script supervisor in charge of continuity.
Production Supervisors are directly in charge of the Editor and all post-production coordinators when the time for their main responsibility comes. Depending on the film their supervising post-production duties could include editing, sound editing, composing the film`s score and music and computer graphics (CGI.) Most productions require some amount of ADR voiceover to increase the quality of the film`s sound and may require reshoots as the Director and Editor work on the final cut.
Supervisors interact with the studio`s executives and legal department about any relevant concerns with the film as it takes its final shape.
Production Supervisors work with the domestic and international distributors to meet the terms of the (usually) prearranged delivery requirements, including ensuring the films get delivered.
They may also be in charge of setting up preview or test screenings of the film and correlating these efforts with the studio or independent marketing teams.
