Final answer:
Auteur Theory suggests that a director's unique personal style and thematic choices are evident throughout their filmography, equivalent to an author's distinctive voice in literature.
Step-by-step explanation:
According to Auteur Theory, a director's film influences can often be seen in their personal style, themes, and cinematic techniques that are consistent across their body of work. The theory posits that the director, rather than the screenwriter, actor, or producer, should be regarded as the "author" of a movie. Each auteur has unique elements that distinguish their films, similar to how an author has a distinctive voice in their writing.
Such elements may include recurring themes, specific genres they favor, their approach to storytelling, and even certain camera angles or lighting they prefer. These signatures often make it possible for audiences to recognize a director's work just by viewing a film's style or technique without beforehand knowledge of its director.
