Which role is responsible for overseeing the overall production process and communication between departments?

The role responsible for overseeing the overall production process and facilitating communication between different departments is the producer. This position involves coordinating the various aspects of a film's development, pre-production, production, and post-production. The producer ensures that the film is completed on time and within budget while maintaining the creative vision of the project.

The producer acts as a central figure, liaising between the various departments—such as the art department, sound, casting, and editing—to ensure smooth collaboration. They facilitate the decision-making process, resolve conflicts, and ensure that all departments are aligned with the project’s goals. This comprehensive oversight is crucial to the success of a film, as it requires effective management and communication skills.

In contrast, the line producer usually focuses on the day-to-day physical aspects of the production, managing the budget and schedules. A unit production manager handles logistical details but is not generally responsible for the broader aspects of the entire production process. The director primarily focuses on the creative vision and direction of the film, guiding the performances and artistic elements without overseeing the overall production management.
