What is the primary purpose of casting in film production?

The primary purpose of casting in film production is to select actors who best fit the roles. This process is crucial as it directly impacts the film’s storytelling, character development, and overall audience engagement. By choosing actors who embody the characteristics of the characters they will portray, casting directors help ensure that the performances resonate with viewers and contribute to the authenticity of the narrative. The chemistry between cast members, their ability to convey emotions, and their alignment with the director’s vision are all essential aspects of successful casting that enhance the film’s overall quality.

Other options such as selecting the film's director, determining the marketing strategy, or creating visual effects do not relate directly to the roles actors play in the film. These aspects are important in their own right within film production but fall outside the primary focus of casting, which is specifically centered around talent selection for acting roles.
