A "First Feature Film" refers to the initial full-length movie produced by a filmmaker or studio. Typically, feature films run for at least 60 minutes and are intended for theatrical release. This milestone is significant in a filmmaker's career, marking their transition from short films or other projects to a more substantial cinematic work. Many renowned directors, such as Steven Spielberg and Martin Scorsese, began their careers with a first feature film that showcased their unique storytelling abilities. These films often reflect the director's style and vision, setting the stage for future projects and establishing their presence in the film industry.
